Abstract

In this study, two new complexes of Cd(II) 4-fluorobenzoate (4-FB)/3-fluorobenzoate (3-FB) with 3-hydroxypyridine (3-HPY) have been synthesized and structural characterizations have been performed by using elemental analysis, FT-IR spectroscopy, and single-crystal X-ray diffraction methods. In both complexes, the metal atom is chelated by two carboxylate groups from two 4- or 3-fluorobenzoate anions and coordinated by two 3-hydroxypyridine (HPY) molecules. In both complexes, an oxygen atom of carboxylate from the adjacent anion bridges to the Cd atom, completing the distorted seven-coordination geometry. The only difference between complexes is the positions of fluorine atoms in fluorobenzoic acids (4-fluorobenzoic acid (complex 1) and 3-fluorobenzoic acid (complex 2)). Antibacterial resistance of two new complexes to some bacteria has been investigated.

具有3- / 4-氟苯甲酸酯和3-羟基吡啶作为共配体的Cd（II）配合物的合成，表征和抗菌活性

摘要

在这项研究中，合成了Cd（II）4-氟苯甲酸酯（4-FB）/ 3-氟苯甲酸酯（3-FB）与3-羟基吡啶（3-HPY）的两种新型配合物，并使用元素进行了结构表征分析，FT-IR光谱和单晶X射线衍射方法。在这两种络合物中，金属原子都被两个4-或3-氟苯甲酸酯阴离子中的两个羧基螯合，并被两个3-羟基吡啶（HPY）分子配位。在这两种配合物中，羧酸盐的氧原子从相邻的阴离子桥到Cd原子，完成了扭曲的七配位几何形状。络合物之间的唯一区别是氟原子在氟苯甲酸（4-氟苯甲酸（络合物1）和3-氟苯甲酸（络合物2）中的位置））。已经研究了两种新复合物对某些细菌的抗菌抗性。
