Models for Copper-Dioxygen Complexes: the Chemistry of Copper(II) with Some Planar Tridentate Nitrogen Ligands

The solution chemistry of Cu(II) with a series of five planar tridentate nitrogen ligands, 2,6-bis(benzimidazol-2-yl)pyridine (bzimpy, 1), 2,6-bis(1-methylbenzimidazol-2-yl)pyridine (mbzimpy, 2), 2,6-bis(benzothiazol-2-yl)pyridine (bzthpy, 3), 2,6-bis(benzoxazol-2-yl)pyridine (bzoxpy, 4), and 2,2′,6′,2″-terpyridyl (terpy, 5) is reported.Electronic and EPR spectra are consistent with the complexes 2+ having essentially tetragonal structure in solution, with the fourth coordination site in the plane of the ligand occupied by solvent. bzthpy and bzoxpy show smaller ligand-field splittings than bzimpy, mbzimpy, and terpy, and are easily decomplexed from the copper.Substitution of the coordinated solvent molecule in the plane of the ligand is observed with Cl- and OH- (provided that the ligand has no acidic protons) for all ligands except terpy.The reaction between 2+ and imidazole has been studied by potentiometric titration in MeCN/H2O 1:1 and shows strong binding of the imidazole in the plane (log K = 4.5 at 25 deg C), and also the formation of an imidazolate-bridged dinuclear species.

Switchable Fe/Co Prussian blue networks and molecular analogues

With the long term objective to build the next generation of devices from the molecular scale, scientists have explored extensively in the past two decades the Prussian blue derivatives and their remarkable physico-chemical properties. In particular, the exquisite Fe/Co system displays tuneable optical and magnetic behaviours associated with thermally and photo-induced metal-to-metal electron transfer processes. Recently, numerous research groups have been involved in the transfer of these electronic properties to new Fe/Co coordination networks of lower dimensionality as well as soluble molecular analogues in order to facilitate their manipulation and integration into devices. In this review, the most representative examples of tridimensional Fe/Co Prussian blue compounds are described, focusing on the techniques used to understand their photomagnetic properties. Subsequently, the different strategies employed toward the design of new low dimensional Prussian blue analogues based on a rational molecular building block approach are discussed emphasizing the advantages of these functional molecular systems.

Bis(saccharinato)palladium(II) and platinum(II) complexes with 2,2?-bipyridine: Syntheses, structures, spectroscopic, fluorescent and thermal properties

New palladium(II) and platinum(II) complexes, cis-[Pd(bpy)(sac)2] (1) and cis-[Pt(bpy)(sac)2] (2), where sac = saccharinate, bpy = 2,2?-bipyridine, have been synthesized and characterized by elemental analysis, UV-Vis, IR, 1H NMR and 13C NMR. The structures of the DMSO solvated complexes are determined by X-ray diffraction. Both complexes are isomorphous and the metal ions are coordinated by two N-bonded sac ligands, and two nitrogen atoms of pyridyl groups of bpy in a cis fashion. The mononuclear species interact each other through weak intermolecular C-H?O hydrogen bonds, C-H?pi and pi?pi interactions leading to three-dimensional supramolecular networks. All complexes exhibit a high thermal stability in the solid state, and are fluorescent in the solution.

Heterogeneous aqueous CO2reduction by rhenium(i) tricarbonyl diimine complexes with a non-chelating pendant pyridyl group

Electrocatalytic CO2reduction in water using a series of chlorotricarbonylrhenium(i) diimine complexes deposited on pyrolytic graphite electrodes is described. Two known CO2reduction catalysts (with diimine = 4,4′-di-tert-butyl-2,2′-bipyridine or 2-(2′-quinolyl)benzimidazole), that are highly active in organic solvent, proved to be only weakly active in water. In contrast, Cl(CO)3Re(L) complexes with tridentate nitrogen-containing ligands (L = 4,4′,4”-tri-tert-butyl-2,2′:6′,2”-terpyridine or 2,6-bis(2-benzimidazolyl)pyridine) were better CO2reduction catalysts. In those Cl(CO)3Re(L) complexes, only two N-atoms of the ligand are coordinated to the rhenium, leaving the third arm of the ligands to support activated, CO2-bound intermediates. The 2,6-bis(2-pyridyl)pyridine (terpy) complex was the most active, with substantial activity at alkaline pH.

A New Paddlewheel-Type Dirhodium-Based Metal-Organic Framework with Deprotonated 2,6-Bis(2-benzimidazolyl)pyridine

The reaction of [Rh2(OAc)4(H2O)2] (OAc=acetate) and 2,6-bis(2-benzimidazolyl)pyridine (bzimpy2H) in EtOH affords two different crystals, orange-red chips (1) and purple blocks (2). Single crystal X-ray diffraction analyses revealed that complex 1 forms a porous two-dimensional framework constructed from [Rh2(OAc)4] and [Rh(bzimpyH)(bzimpy)], whereas complex 2 forms a bis-bzimpy2H-adducted discrete complex, [Rh2(OAc)4(bzimpy2H)2]. Interestingly, the color of the crystalline powder of complex 1 changes from orange-red to yellow-brown immediately upon removal of guest solvents from the pores of complex, and dried complex 1 (yellow-brown state) can recover to its orange-red state by soaking in EtOH at room temperature.

Nickel(II) complexes of a 3N ligand as a model for diketone cleaving unusual nickel(II)-dioxygenase enzymes

Diketone substrate bound nickel(ii) complexes of 2,6-bis(1-methylbenzimidazolyl)pyridine have been synthesized and characterized as relevant active site models for unusual diketone cleaving Ni(ii)-dependent enzymes Ni-ARD and DKDO. The average Ni-Npy/benzim bond distances (2.050-2.107 A) of model complexes are almost identical to the Ni-NHis bond distances of NiII-ARD (2.02-2.19 A). The reaction of these adducts with dioxygen exhibited C-C cleavage with the rate of kO2, 5.24-73.71 ¡Á 10-3 M-1 s-1.

Recyclable Cu(II)-Coordination Crosslinked Poly(benzimidazolyl pyridine)s as High-Performance Polymers

Crosslinked high-performance polymers have many industrial applications, but are difficult to recycle or rework. A novel class of recyclable crosslinking Cu(II)-metallo-supramolecular coordination polymers are successfully prepared, which possess outstanding thermal stability and mechanical property. More importantly, the Cu2+ coordination interactions can be further removed via external pyrophosphate to recover the linear polymers, which endow the crosslinking polymers with recyclability.
