Abstract
合成了1种含四氯合钴配阴离子的4-氯苄基吡啶季铵盐[4-ClBzPy]2[CoCl4];利用元素分析仪、X射线单晶衍射仪以及紫外光谱仪和红外光谱仪等分析了其组成、晶体结构及光谱学性质;利用电导仪测定了[4-ClBzPy]2[CoCl4]的电导,并检测了其对金黄色葡萄球菌和大肠杆菌的抗菌活性.结果表明,合成的[4-ClBzPy]2[CoCl4]季铵盐为单斜晶系,P2(1)/c空间群,晶胞参数为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)nm3,Z=2,Dc=1.470g/cm3,GOOF=1.007,R1=0.041 8,wR2=0.100 2.与此同时,季铵盐[4-ClBzPy]2[CoCl4]对金黄色葡萄球菌和大肠杆菌均具有较好的抗菌活性.
