摘要

Seven new Cu(II) and Co(II) coordination compounds are synthesised with the general formula M(L)(X)_2(Y)_z, in which L stands for the known ligand bis(2-benzimidazolyl)propane and for the novel ligands bis(2-benzimidazolyl)-2-butane and bis(2-benzimidazolyl)-3-butane, M = Cu(II) and Co(II), X = Cl and Br, Y = water and/or ethanol and z varies from 0 to 1. The single-crystal X-ray structural analyses as well as some spectroscopic and magnetic measurements have been performed. Each Cu(II) and Co(II) is surrounded by a didentate chelating ligand and two halide anions resulting in a distorted tetrahedral geometry with M-N distances varying from 1.975 to 2.204 A and M-Cl distances from 2.215 to 2.268 A. Some structural data with these compounds are compared with related compounds in the literature.
