Nitrate- and nitrite-ligated 3,6-bis(imidazolyl)pyridazine-bridged dinuclear copper(II) cations with copper-copper separations similar to that in Achromobacter cycloclastes nitrite reductase

The 4,4?-bipyridine (4,4?-bipy) and 3,6-bis(imidazolyl)pyridazine (bimpydz) bridged dinuclear copper(II)-diethylenetriamine (dien) complexes, [{Cu(dien)}2(mu-diimine)][NO3] 4·xH2O (diimine = 4,4-bipy, x = 21; diimine = bimpydz, x = 05), [{Cu(dien)}2(mu-diimine)][BF4]4·4MeCN (diimine = 4,4-bipy 2 or bimpydz 6) and [{Cu(dien)}2(mu-bimpydz)]Cl4·4H2O 4, have been synthesised and characterised. Reaction of the tetrafluoroborates, 2 and 6, with NaNO2 yields the nitrites [{Cu(dien)}2(mu-diimine)][NO2][BF4] 3·xMeCN (diimine = 4,4-bipy, x = 03; diimine = bimpydz, x = 0.57). Neither the chloride nor the nitrates react with NaNO2. Structural analysis of complexes 5 and 7 has shown that although they are both based on the dinuclear cationic unit, [{Cu(dien)}2(mu-bimpydz)]4+, in 5 the bimpydz bridge adopts a transoid arrangement of imidazole molecules, whereas in 7 it adopts a cisoid arrangement, giving Cu … Cu separations of 13.28 and 12.88 A, respectively. In 5, the dications are linked by two axially co-ordinated nitrate anions, one strongly bound, the other very weakly bound, to give chains with a ladder-type motif. In 7, the dications are bridged by mu-nitrito-kappaO:kappaN moieties to form a chain with helical geometry. The copper(II)-nitrite interaction is novel; the anion bridges the weakly binding axial positions of two square-pyramidal copper atoms using the nitrogen lone pair and the syn lone pair of an oxygen.

Reversible five-coordinate ? six-coordinate transformation in cobalt(II) complexes

The heterocyclic ligands 2,6-bis(pyrazol-1-yl)pyridine (L1) and 2,6-bis(benzimidazol-2-yl)pyridine (L2) and their cobalt(II) complexes were synthesized. The blue five-coordinate complex [Co(L1)Cl2] isolated initially from the reaction mixture rapidly absorbed water vapour from the atmosphere to yield the pink six-coordinate complex [Co(L1)(H2O)3]Cl2. This change is reversible upon desiccation or transferring [Co(L1)(H2O)3]Cl2 into acetonitrile. The five coordinate complex [Co(L2)Cl2], however, remains stable under similar conditions. The structures of the complexes [Co(L1)Cl2], [Co(L1)(H2O)3]Cl2 and [Co(L2)Cl2] have been determined by x-ray crystallography. The magnetic susceptibilities and the electronic spectra for [Co(L1)Cl2], [Co(L2)Cl2] and [Co(L1)(H2O)3]Cl2 are presented.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Structural studies of thermal- and light- induced transitions in iron(II) spin-crossover complexes

Since the spin-crossover (SCO) effect was first discovered, considerable efforts have been made to study compounds that exhibit this phenomenon. Herein we present a selection of our most exciting results from structural studies carried out on some of the fascinating iron(II) SCO compounds we have investigated over the past few years. We discuss a range of compounds from mononuclear to bimetallic polymeric complexes.

Luminescent Electropolymerizable Ruthenium Complexes and Corresponding Conducting Metallopolymers

Tris(2,2?-bipyridyl)ruthenium(II) dichloride [Ru(bpy)3Cl2] and analogous complexes have been studied extensively in the literature due to their luminescent and photochemical properties as well as their excited-state lifetimes. Conducting polymers with similar ruthenium groups have also been investigated for various applications. In this study, syntheses of four ruthenium complexes with a polymerizable tridentate ligand, bis[4-[2-(3,4-diethylenedioxy)thiophene]pyrazol-1-yl]pyridine (EDOT2NNN), and with bidentate ligands, two of which were anionic (hfac: 1,1,1,5,5,5-hexafluoro-2,4-pentanedione; dbm: dibenzoylmethane) and two of which were neutral (bpy: 2,2?-bipyridyl; phen: 1,10-phenanthroline), were achieved for potential OLED/PLED applications. Saturated CH2Cl2 solutions of monomers were oxidatively and electrochemically polymerized, and the scan rate dependences of the polymers were measured. UV-vis spectroscopic characterizations of the complexes and the EDOT-functionalized ligand were obtained. [Ru(EDOT2NNN)(phen)(Cl)](PF6) was electropolymerized on an ITO (indium tin oxide)-coated glass surface to obtain the solid-state absorption spectrum of the corresponding polymer. Photophysical data for each complex, i.e., excitation and emission spectra at 77 K and RT, in EtOH/MeOH (4:1) and in 2-MeTHF (dry, air-free, and aerated), quantum yield, and luminescence lifetime have been measured. The radiative and nonradiative decay constants as well as the oxygen quenching rate coefficient for each complex were calculated. [Ru(EDOT2NNN)(phen)(Cl)](PF6), having the highest quantum yield of phosphorescence and the longest lifetime, was electropolymerized on an ITO-coated glass surface to obtain the solid-state excitation and emission spectra of the corresponding polymer. Luminescence studies of the polymer had promising results for photoluminescence.
