The syntheses and characterisation of chromium(III) complexes with tris(2-benzimidazolylmethyl)amine (ntb), 2-guanidinobenzimidazole (2gb), 2,6-bis(2-benzimidazolyl)pyridine (bbimpy) and 2-(2-pyridyl)benzimidazole (2pb), of composition [Cr(ntb)Cl2]Cl·4.5H2O (1), [Cr(2gb)3]Cl[ZnCl4]·CH3OH (2), [Cr(2gb)3]Cl3·4H2O (3), [Cr2(2gb)4(μ-OH)2](ClO4)4·5H2O (4), [Cr(b-bimpy)Cl3] (5) and [Cr(2pb)2Cl2]Cl·C2H5OH·0.5H2O (6) are presented. The compounds are obtained from Cr(III)in alcoholic solution, or a Cr(II) aqueous acidic solution. The latter were carried out under air-free conditions. The reaction of 2gb with Cr(II) in aqueous solution yielded a dinuclear compound. The X-ray crystal structures of 1 and 4 are discussed. (C) 2000 Elsevier Science Ltd.
