The mode of binding of dimethyl sulphoxide (dmso) in cations of the type + has been examined by i.r. and 1H n.m.r. spectroscopy.Infrared spectra of the complexes in the solid state indicate that dmso binds through oxygen in the palladium(II) adducts containing bipy and phen, and through sulphur in the other cases.Proton n.m.r. spectra in CD3NO2 solution show that the complexes in which dmso is S-bonded in the solid state retain their structure in solution, while those containing O-bonded dmso equilibrate to a mixture of O- and S-bonded isomers whose composition depends upon the nature of the chelated diamine.Interconversion between the two isomers is slow on the n.m.r. time-scale, while exchange of S- and O-bonded dmso is fast.The crystal and molecular structures of , (1), and , (2) have been determined by X-ray diffraction: (1) crystallizes in the triclinic space group P1 with Z = 2, a = 10.318(1), b = 12.503(1), c = 7.436(1) Angstroem, and alpha = 95.40(1), beta = 109.10(1), gamma = 109.75(1) deg; (2) crystallizes in the monoclinic space group P21/n with Z = 4, a = 9.960(1), b = 8.652(1), c = 14.152(2) Angstroem, and beta = 92.25(1) deg.The structures were solved by Patterson and Fourier methods and refined by full-matrix least squares to R = 0.026 and 0.024 for (1) and (2), respectively.The co-ordination geometry of the metal atom is square planar in both cases; in complex (1) the dmso ligand is oxygen bonded, while in (2) it is sulphur bonded.The geometries of O- and S- bonded dmso differ considerably: in (2) the S=O distance, O-S-C and C-S-C angles correspond to the geometry of free dmso; in (1) the S=O distance is intermediate between single and double bond lengths, the two O-S-C angles increase by some 7 deg with respect to S-bonded dmso, while the C-S-C angle increases only by 3.6 deg.

Spin-crossover (SCO) molecular solids are valued switchable materials for their common abrupt and reversible thermal transitions, large thermal hysteresis, or guest-dependent effects. These properties usually involve crystallographic transitions coupled to the SCO events. These phenomena are of great value for the understanding of solid-state transformations and also for exploiting them. We present here a lattice of the complex [FeL(bbp)](ClO4)2 (1; L and bbp are tris-imine ligands) featuring an unprecedented rich succession of SCO and crystallographic phase transformations. Magnetometry measurements unveil a thermally irreversible sequence of spin conversions that delineate four different thermal pathways. All of these are single-crystal-to-single-crystal processes and can thus be monitored by single crystal X-ray diffraction using one unique specimen. Fresh crystals of 1 contain one molecule of acetone per Fe center (1·ac) that abandons the lattice upon warming at the same time that a SCO from an ordered mixed spin state (1:1 high spin/low spin; HS/LS) to a fully HS state, 1alpha, occurs. This crystallographic phase, accessed through a template effect by the solvent, converts into another one, 1beta, upon cooling, as triggered by a HS to LS SCO. Warming of 1beta induces a new SCO (LS to ordered HS/LS) coupled to another crystallographic phase transition, 1beta ? 1gamma. The fully HS state of 1gamma can not be reached before decomposition of the compound. Instead, this phase cycles between the HS/LS and the LS states through superimposable pathways, different from that of the prerequired 1beta ? 1gamma phase change. Analysis of the thermal variation of the free energy, G, through density functional theory methods provides trends in agreement with the observation of these transformations and clarifies the possible metastable nature of the various phases identified. This unique behavior allows the access to four different magnetic responses depending on the thermal history of the sample, within a given range of temperatures near the ambient conditions.

The complexes (L2 = 1,4-dimethoxy-2-diphenylphosphinobenzene), + (bipy = 2,2′-bipyridine) and (mpy = 4-methylpyridine) have been prepared and their reactions with BBr3 studied.The first two complexes afforded products resulting from protolytic cleavage of the phosphinohydroquinone ligand whereas reactions of the last with BBr3 produced (H2pphq = H2L1 = 2-diphenylphosphinohydroquinone) when quenched with methanolic sodium carbonate or, when quenched with methanol alone, a mixture which contains the novel tetrameric cluster <4> and slowly deposits an unexpected phosphinephosphinite complex, cis->*H2O, on standing.The crystal structures of the last two complexes have been determined.The palladium tetramer was also formed when was treated with hydrobromic acid.The NMR spectra suggest that in solution the tetramer is in equilibrium with monomeric solvato complexes, (solv = solvent).

The judicious selection of pairs of benzimidazole-ligated ruthenium complexes allowed the construction of a rechargeable proton-coupled electron-transfer (PCET)-type redox battery. A series of ruthenium(II) and -(III) complexes were synthesized that contain substituted benzimidazoles that engage in PCET reactions. The formation of intramolecular Ru-C cyclometalation bonds stabilized the resulting ruthenium(III) complexes, in which pKa values of the imino N-H protons on the benzimidazoles are usually lower than those for the corresponding ruthenium(II) complexes. As a proof-of-concept study for a solution redox battery based on such PCET reactions, the charging/discharging cycles of several pairs of ruthenium complexes were examined by chronopotentiometry in an H-type device with half-cells separated by a Nafion membrane in unbuffered CH3CN/H2O (1/1, v/v) containing 0.1 M NaCl. During the charging/discharging cycles, the pH value of the solution gradually changed accompanied by a change of the open-circuit potential (OCP). The changes for the OCP and pH value of the solution in the anodic and cathodic half-cells were in good agreement with the predicted values from the Pourbaix diagrams for the pairs of ruthenium complexes used. Accordingly, the careful selection of pairs of ruthenium complexes with a sufficient potential gradient and a suitably large pKa difference is crucial: the charge generated between the two ruthenium complexes changes the OCP and the pH difference between the two cells in an unbuffered solution, given that the PCET reactions occur at both electrodes and that discharging leads to the original state. Because the electric energy is stored as a pH gradient between the half-cells, new possibilities for PCET-type rocking-chair redox batteries arise.

A new class of luminescent alkynylplatinum(II) complexes of tri-dentate bis(N-alkylbenzimidazol-2?-yl)-pyridines (bzimpy), [Pt(R,R?-bzimpy)- (C?C-R?)]X (X = PF6, OTf), and one of their chloro precursor complexes, [Pt(R,R?-bzimpy)Cl]PF6, have been synthesized and characterized; one of the alkynyl complexes has also been structurally characterized by X-ray crystallography. Electrochemical studies showed that the oxidation wave is alkynyl ligand-based in nature with some mixing of the metal center-based contribution, whereas the two quasi-reversible reduction couples are mainly bzimpy-based reductions. The electronic absorption and luminescence properties of the complexes have also been investigated. In solution, the high-energy and intense absorption bands are assigned as the pi-pi* intraligand (IL) transitions of the bzimpy and alkynyl ligands, whereas the low-energy and moderately intense absorptions are assigned to an admixture of metal-to-ligand charge-transfer (MLCT) (dpi(Pt) ?pi*(R,R?-bzimpy)) and ligand-to-ligand charge-transfer (LLCT) (pi-(C?C-R?) ?* (R,R?-bzimpy)) transitions. Upon variation of the electronic effects of the arylalkynyl ligands, vibronic-structured or structureless emission bands, originating from triplet metal-perturbed intraligand (IL) or an admixture of triplet metal-to-ligand charge-transfer (MLCT) and ligand-to-ligand charge-transfer (LLCT) excited states respectively, were observed in solution. Interestingly, two of the complexes showed a dual luminescence that was sensitive to the polarity of the solvents. Upon cooling from 298 K to 155 K, drastic color, UV/Vis, and luminescence changes were observed in a butyronitrile solution of 1, and were ascribed to the formation of aggregate species through Pt … Pt and pi-pi stacking interactions. DFT and time-dependent DFT (TD-DFT) calculations have been performed to verify and elucidate the results of the electrochemical and photophysical properties.

By introducing 2,6-bis(2-benzimidazolyl)pyridyl and 2,6-di-(pyrazol-3-yl)pyridine derivatives as ligand in the reaction system, three new transition-metal coordination complexes have been successfully synthesized, namely, [Co(HL1)2] (1), [Ni(HL1)2] (2), and [Ni3(H2L2)2(HL2)2](OH)3(Ac)H2O (3) (H2L1=2,6-bis(benzimidazol-2-yl)pyridine and H2L2=2,6-di-(5-phenyl-1H-pyrazol-3-yl)pyridine). They are all characterized by elemental analysis, IR spectroscopy, UV absorption spectroscopy, thermogravimetric analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. Structural analysis shows that the structures of complexes1 and 2 are similar. They are constructed from one metal (Co, Ni) atom and two 2,6-bis(benzimidazol-2-yl)pyridine ligands (HL1-); the HL1- ligand is in the tridentate coordination mode with N3 donors. Complex3 is a trinuclear Ni complex with four 2,6-di-(5-phenyl-1H-pyrazol-3-yl)pyridine (H2L2) ligands, in which the H2L2 possesses two coordination fashions: terminal tridentate and bridging tetradentate. In addition, the surface photovoltage spectroscopy and photocatalytic activities of complexes1-3 were investigated in detail. The results reveal that complex3 possesses higher photocatalytic activity. A coordinated approach: The coordination complexes [Co(HL1)2], [Ni(HL1)2], and [Ni3(H2L2)2(HL2)2](OH)3(Ac)H2O (H2L1=2,6-bis(benzimidazol-2-yl)pyridine, H2L2=2,6-di-(5-phenyl-1H-pyrazol-3-yl)pyridine) have been synthesized and characterized systematically. Surface photovoltage spectroscopy indicates p-type semiconductor characteristics and the ability to act as a photocatalyst to degrade the dye methylene blue (MB; see figure).
