Abstract

Three newly synthesized copper(II) complexes with the general formula [CuL], where L is the dianionic form of N,N′-bis(3,5-difluorosalicylidene)ethane-1,2-diamine (H₂L¹) for 1, N,N′-bis(3,5-difluorosalicylidene)propane-1,3-diamine (H₂L²) for 2, and N,N′-bis(3,5-difluorosalicylidene)-2-hydroxy-1,3-propanediamine (H₂L³) for 3, have been obtained and structurally characterized by spectroscopic method and single-crystal X-ray determination. The Cu atoms in the complexes are in square planar coordination, with the two imino N and two phenolate O atoms of the Schiff base ligands. The in vitro antimicrobial activities of the compounds indicate that they are interesting antibacterial agents.

摘要

三个新合成的通式为[CuL]的铜（II）配合物，其中L为N，N'-双（3,5-二氟水杨亚基）乙烷-1,2-二胺（H ₂ L ¹）的二价阴离子形式1，N，N' -双（3,5-二difluorosalicylidene）丙烷-1,3-二胺（H ₂大号²）为2，和N，N' -双（3,5-二difluorosalicylidene）-2-羟基1,3-丙二胺（H ₂ L ³）3通过光谱法和单晶X射线测定，已经获得了Al 2 O 3，并对其结构进行了表征。配合物中的铜原子与席夫碱配体的两个亚氨基N和两个酚盐O原子呈方形平面配位。这些化合物的体外抗菌活性表明它们是有趣的抗菌剂。
