摘要：

A hexapositively charged tetrahedral geometry Co(II) complex was synthesized using a new positively charged ligand prepared quaternizing 4,4'-bipyridine by 1-bromobutane. It is characterized by spectrometry (H-1 NMR, ESI MS,Uv-Vis, ICP OES), carbon, hydrogen and nitrogen (CHN) elemental analysis, halide estimation and conductivity measurement. The complex showed significantly high molar conductivity value in water (640.83 S mol(-1) cm(2)). Its in vitro biological activities were tested on one gram-positive (Staphylococcus aureus) and one gram-negative (Klebsiella pneumoniae) bacteria. It was found active against both bacteria with improved and better activity against the latter.
