Abstract

A number of bimetallic thiocyanato-bridged complexes of cations [M(NH2X)6]2+ and [M(en)3]2+ with anions [Co(NCS)4]2– are prepared. Their structure has been investigated in terms of FT-IR, 13C NMR and UV-vis spectroscopy, metal analysis, magnetic and conductance studies. The complexes are proposed to have the following compositions, [M(NH2X)5][Co(NCS)4] and [{M(en)2}{Co(NCS)4}]n (where M=Cu, Ni, Zn, Cd; X=H, Ph; en=ethylenediamine). The general feature results from i. a combination of the bridging thiocyanate ligand, ii. the distorted environments of cobalt(II) and iii. regular octahedral geometry of cations. The antibacterial activity of the prepared complexes against the gram positive, Bacillus cereus and gram negative Salmonella typhi, Pseudomonas alruginosa, Escherichia coli pathogens has also been investigated.
