Abstract

Two new Schiff base copper(II) complexes, [Cu₂L₂] (I) and [Cu₂L(NCNCN)₂]_n (II), where L is the dianionic form of N,N'-bis(5-fluorosalicylidene)-1,3-propanediamine (H₂L), were synthesized and characterized by elemental analyses, infrared and electronic spectroscopy, and single crystal X-ray determinations (CIF files CCDC. nos. 2000415 (I) and 2000416 (II)). Complex I is a phenolate bridged dinuclear copper(II) compound. Complex II is a phenolate and dicyanoamide bridged polynuclear copper(II) compound. In both complexes, the Cu atoms are in square pyramidal coordination. The Schiff base ligand coordinates to the Cu atoms through the phenolate O and imino N atoms. The Schiff base H₂L and the two complexes showed high selectivity and antimicrobial activities against a number of the bacteria and fungi.

N，N'-双（5-氟水杨基）-1,3-丙二胺衍生的铜（II）配合物的合成，晶体结构和抗菌活性

摘要

两个新的席夫碱铜（II）配合物[Cu ₂ L ₂ ]（I）和[Cu ₂ L（NCNCN）₂ ] _n（II），其中L是N，N'-双（5- ）的_二价阴离子形式。合成并通过元素分析，红外和电子光谱法以及单晶X射线测定（CIF文件CCDC。no。2000415（I）和2000416（II））合成并表征了氟水杨基亚基）-1,3-丙二胺（H ₂ L）。）。配合物I是酚盐桥接的双核铜（II）化合物。复杂二是酚盐和双氰胺桥连的多核铜（II）化合物。在这两种络合物中，Cu原子均处于方形锥体配位状态。席夫碱配体通过酚盐O和亚氨基N原子与Cu原子配位。Schiff碱H ₂ L和这两种配合物对多种细菌和真菌显示出高选择性和抗菌活性。
