Abstract
Abstract The reaction of pyridine-2-carbonitrile with copper(II), cobalt(II) and nickel(II) salts in methanol solution led to the formation of solid complexes containing O-methyl-pyridine-2-carboximidate as a ligand (L). Seventeen compounds with general formulae [MX2L], [MXL2]X, [MX2L2] or [ML3]X2, where X = Br−, Cl−, NCS−, ClO4− and M = CuII COII, NiII, have been obtained under various reaction conditions. Their stereochemistry and the mode of ligand coordination have been determined by spectral, magnetic and conductometric measurements. The crystal structure of [Ni(O-methylpyridine-2-carboximidate)3]Br2·4H2O was determined by X-ray diffraction techniques. The influence of the metal(II) atom on the composition and the stereochemistry of solid complexes is briefly discussed.
