Abstract

New vanadium(II) alcoholates, VBr 2·6EtOH, VCl 2·4EtOH and VCl 2·2EtOH have been prepared and used with hydrated vanadium(II) salts for the synthesis of vanadium(II) heterocyclic amine complexes. Magnetic and reflectance spectra data show that complexes formulated as [VL 4X 2], where L = a heterocyclic amine, have a distorted octahedral structure whereas complexes of the type [VL 6]X 2 have octahedral geometry (X = Cl, Br and I). The amines used in this work were pyrazole (pz), imidazole (iz), 2-methylimidazole (2-miz), benzimidazole (biz) and isoquinoline (iq).
