a new quaternary ammonium salt containing [CoCl4 ]2 - anion and 4-chlorobenzyl pyri-dine cation ,[4-ClBzPy ]2 [CoCl4 ] ,was synthesized . The composition ,crystal structure and spectrometric properties of as-synthesized product were analyzed by elemental analysis ,single crystal X-ray diffraction ,ultraviolet-visible light spectrometry ,and infrared spectrometry .The conductivity of [4-ClBzPy]2 [CoCl4 ] was measured with an electric conductivity meter ,and its antimicrobial activities against Escherichia coli and Staphylococcus aureus were determined . Results show that as-synthesized [4-ClBzPy]2 [CoCl4 ] quaternary ammonium salt crystallizes in the monoclinic system of P2(1)/c space group ,with a = 0 .769 5(13) nm ,b = 1 .895 1(3) nm ,c = 0 .946 3(15) nm ,β = 93 .183(2)° ,V = 1 .378 0(4) nm 3 ,Z = 2 ,Dc= 1 .470 g/cm 3 , GOOF = 1 .007 ,R1 = 0 .041 8 ,and wR2 = 0 .100 2 .In the meantime ,the quaternary ammoni-um salt exhibits good antibacterial effect against Escherichia coli and Staphylococcus aureus .
