The new complexes of 4-methylesculetin (H2mesc), [Zn2(bpy)2(mesc)2], [Zn(PPh3)2(mesc)], Na2[MoO2(mesc)2], (PPh4)2[Mo2O5(mesc)2], [Pd(bpy)(mesc)], [Pd(phen)(mesc)], [Pd(PPh3)2(mesc)], [Pt(PPh3)2(mesc)] and [Ag(bpy)2]. (bpy)H2mesc(NO3), are reported. The complexes were characterized on the bases of elemental analysis, spectroscopic (IR, UV-Vis, mass, 1H, 13C and 31P NMR) and physical (conductivity and thermal) techniques. The ligand (mesc2-) behaves in a binegative bidentate fashion, chelating the metal ions through the deprotonated hydroxy oxygen atoms, except in case of Ag(I), where it was found outside the coordination sphere of the complex. The X-ray crystal structure of [Zn2(bpy)2(mesc)2] has been determined. The bond length of Zn-O(7) is shorter than Zn-O(6). A theoretical study on H2mesc and its dianion mesc-2 was undertaken through computational conformational analysis, indicating the higher basicity of O(7) with respect to O(6). H2mesc and the complexes have been tested as anti-neoplastic agents against human prostate cancer (DU 145) and human breast cancer (MDA-MB231) cell lines.

The reaction between two equivalents of N-(2-hydroxyphenyl)-p-toluenesulfonamide (H2sulf) and [N3P3(biph)2Cl2] (H2biph = 2,2?-biphenol) produces the compound bis(2,2?-biphenylato)bis(2-oxyphenyl)-p-toluenesulfonamide cyclotriphosphazene (H2L) containing two geminal Hsulf moieties. Further reaction of H2L in basic conditions results in the removal of the sulfonamide arm and the slow formation of a novel phosphazene containing the spirocyclic sulf moiety. When this occurs in the presence of [Pd(bpy)Cl2] the reaction is facile and the new complex [Pd(bpy)(sulf)] (2) is also formed. Compounds H2L, 1 and 2 have all been characterised by single crystal X-ray crystallography.

The new palladium and platinum complexes with 3-hydroxypicolinic acid (HpicOH) [M(PPh3)2Cl(picOH)]·CHCl3, [M(bipy)(picOH)]Cl [M = Pd(II) or Pt(II)], K[PdCl(picOH)2] and [Pt(picOH)2] and the new rhenium complexes [ReOI2(PPh3)(picOH)] and [ReO(PPh3)(picOH)2]I have been prepared. The crystal structures of [M(PPh3)2Cl(picOH)]·CHCl3 [M = Pd(II) 1 or Pt(II) 2] and [ReOI2(PPh3)(picOH)] 3 were determined by X-ray diffraction. Complex 3 exhibits a distorted octahedral geometry with the picOH- ligand showing N,O-chelation with a small bite angle O-Re-N of 74.8(3). In complexes 1 and 2 the metal centre is surrounded by a NP2Cl donor set in a distorted square planar arrangement. Therefore, the picOH- ligand is bound through the nitrogen atom, but the distances found between the metal and the carboxylate oxygen [Pd···O(71) 2.773(5) A or Pt···O(71) 2.734(4) A] suggest a [4 + 1] coordination consistent with N,O-chelation for palladium and platinum centres. Infrared, Raman, 1H and 13C-{1H} NMR spectroscopic data for the complexes are consistent with the crystallographic results. In the solid state the complex units of 1 and 3 are aggregated in centrosymmetric dimers based on C-H···Cl or C-H···O hydrogen bonding interactions between the chlorine of the Pd-Cl bond (in 1) or the phenolic oxygen of the picOH- anion (in 3) and a hydrogen atom of a phenyl group of a PPh3 ligand.

Penta-coordinated mononuclear copper(II) complex of tridentate 2,6-bis-(benzimidazolyl)pyridine (L) formulated as [Cu(L)(H2O)2](NO3)2, 1 was synthesized and isolated in pure form. The complex was characterized by physico-chemical and spectroscopic methods, as well as single crystal X-ray diffraction analysis. The structural study shows the metal in a highly distorted square pyramidal geometry [trigonality index tau = 0.1425] that comprises two aqua molecules in the first coordination sphere. The crystal packing of 1 shows a 3D polymer formed through H-bonds involving aquo ligands, NH benzimidazole groups and nitrate anions. On reaction with pseudohalides in acetonitrile at ambient temperature complex 1 changed to mono cationic copper(II) derivatives [Cu(L)(X)(H2O)]NO3 [X = SCN- (2a) and N3- (2b)]. These copper(II) complexes have been isolated from the reaction mixtures and characterized by physico-chemical and spectroscopic tools. The interaction of complex 1 with calf thymus DNA (CT-DNA) has been investigated by using absorption and emission spectral studies, the binding constant (Kb) and the linear Stern-Volmer quenching constant (Ksv) have been determined.

Variable-temperature NMR spectroscopy showed that the complexes undergo fluxional processes in solution, which were confirmed, by DFT calculations, to be (E)-pyramidal inversion at the chalcogen centre rather than ring-flip or (E)-dissociation processes.

In this work, the effects of ligand field strength as well as the metal coordination geometry on magnetic anisotropy of pentacoordinated CoII complexes have been investigated using a combined experimental and theoretical approach. For that, a strategic design and synthesis of three pentacoordinate CoII complexes [Co(bbp)Cl2]·(MeOH) (1), [Co(bbp)Br2]·(MeOH) (2), and [Co(bbp)(NCS)2] (3) has been achieved by using the tridentate coordination environment of the ligand in conjunction with the accommodating terminal ligands (i.e., chloride, bromide, and thiocyanate). Detailed magnetic studies disclose the occurrence of slow magnetic relaxation behavior of CoII centers with an easy-plane magnetic anisotropy. A quantitative estimation of ZFS parameters has been successfully performed by density functional theory (DFT) calculations. Both the sign and magnitude of ZFS parameters are prophesied well by this DFT method. The theoretical results also reveal that the alpha ? beta (SOMO-SOMO) excitation contributes almost entirely to the total ZFS values for all complexes. It is worth noting that the excitation pertaining to the most positive contribution to the ZFS parameter is the dxy ? dx2-y2 excitation for complexes 1 and 2, whereas for complex 3 it is the dz2 ? dx2-y2 excitation.

We show a marked tendency of Fe(II) to form heteroleptic [Fe(L)(L?)](ClO4)2 complexes from pairs of chelating tris-imine 3bpp, tpy, or 2bbp ligands. New synthetic avenues for spin crossover research become thus available, here illustrated with three new heteroleptic compounds with differing magnetic behaviors: [Fe(H4L1)(Cl-tpy)](ClO4)2·C3H6O (1), [Fe(H2L3)(Me3bpp)](ClO4)2·C3H6O (2), [Fe(H4L1)(2bbp)](ClO4)2·3C3H6O (3). Structural studies demonstrate that 1 is in the low-spin (LS) state up to 350 K, while complexes 2 and 3 are, by contrast, in the high-spin (HS) state down to 2 K, as corroborated through magnetic susceptibility measurements. Upon exposure to the atmosphere, the latter exhibits the release of three molecules of acetone per complex, turning into the solvent-free analogue [Fe(H4L1)(2bbp)](ClO4)2 (3a), through a single-crystal-to-single-crystal transformation. This guest extrusion process is accompanied by a spin switch, from HS to LS.

Synthetic Route of 14220-64-5, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14220-64-5, Name is Bis(benzonitrile)palladium chloride, molecular formula is C14H10Cl2N2Pd.

Two bis-tridentate pincer complexes [Ru(H2bip)(Mebib)](PF6)2 (1(PF6)2) and [Ru(H2bip)(H2bib)](PF6)2 (2(PF6)2) were prepared and studied, where H2bip is 2,6-bis(benzimidazol-2-yl)pyridine, Mebib is the 2-deprotonated 1,3-bis(N-methylbenzimidazol-2-yl)benzene, and H2bib is 2-deprotonated 1,3-bis(benzimidazol-2-yl)benzene. These complexes were isolated as cyclometalated Ru(III) salts with a [(NCN)(NNN)] coordination due to a low Ru(III/II) redox potential. Complex 1(PF6)2 has two N?H protons on the NNN ligand side, while complex 2(PF6)2 has four N?H protons. Absorption spectral analysis showed that two deprotonation steps were distinguished for 1(PF6)2 with pKa1 and pKa2 of 3.46 and 5.88, respectively. In comparison, four deprotonation steps were observed for 2(PF6)2 with four pKa values of 3.45, 5.95, 8.95, and 10.98, respectively. When the solution was changed from acidic to basic, the Ru(III/II) redox wave of 1(PF6)2 and 2(PF6)2 shifted from +0.20 V vs Ag/AgCl to a less positive region by 540 and 850 mV, respectively. These studies suggest that the electronic absorption and electrochemical properties of these complexes are very sensitive to pH effect.
