The preparation and the characterization of Ni2+ and Fe2+ complexes of the neutral, N-4(-) non-macrocyclic Shiff base ligand, L = 1,2-bis-(2'-pyridylmethyleneimino)benzene of formulae FeLCl2 and [NiL(H2O)(2)]Cl-2(-) are reported. The structure of the Ni complex, [NiL(H2O)(2)]Cl-2, has been determined by X-ray diffraction methods. The nickel atom has a six coordinate NiN4O2 chromophore with distorted octahedral coordination. The ligand L acts as tetradentate chelate, with the ligated atoms in an essentially planar arrangement around the metal with the remaining-axial coordination sites occupied by water ligands. In addition a series of ligand-bridged LMCl2 oligomeric complexes of the type {[LME]Cl-2}(n) (M = Ni, Fe, Cu and E = pyrazine, 4,4'-bipyridine, 1,4-dicyanobenzene, 1,4-cyanopyridine), have been synthesized and characterized by elemental analysis, solid state conductivity, magnetic susceptibility measurements and IR, UV-VIS and ES-MS spectroscopic techniques. Doping of these complexes with iodine exhibited conductivities in the solid state comparable to similar dimethylglyoxime derivative complexes. (C) 1998 Elsevier Science Ltd. All rights reserved.
