摘要
近几十年来,过渡金属配合物药物研究不断取得突破性成就,其在抗菌、抗肿瘤和抗病毒等方面都具有一定优势,具有很大的开发潜力和良好的应用前景。
本文基于分子设计的思想,以二价的Cu、Co、Mn等为中心离子,均苯四甲酸、1,4-双(咪唑-1-基)丁烷(bbi)、对羟基苯甲酸等为配体,合成了4种新型过渡金属配合物,并通过X-射线单晶衍射、元素分析、IR等对晶体结构进行了表征。
配合物1:经X-射线单晶衍射,配合物1中存在两个独立的铜中心,两个二价铜中心都是畸变的八面体构型。均苯四甲酸作为桥连配体分别通过羧基上的氧与相邻的两个Cu(1)中心配位,形成一维无限链状结构[Cu(C10H2O8)(C3H4N2)2(H2O)2]n。而Cu(2)中心原子分别与四个咪唑及两个水配位形成零维结构片段Cu(C3N2H4)2(C2N3H3)2(H2O)2。
配合物2:经红外、元素分析和热重分析,利用特征峰可以推断出该配合物既含有对羟基苯甲酸,又含有bbi,所以可以确定配合物2是钴的对羟基苯甲酸和bbi配合物。
配合物3:经红外、元素分析,可以确定配合物3是钴的对羟基苯甲酸和bbi配合物。
配合物4:经红外分析以及配合物的外观表征可以推断配合物2是钴的对羟基苯甲酸和bbi配合物。

Abstract
In recent decades, transition plexes drug research breakthrough achievements unceasingly, its antibacterial, antitumor and antivirus, etc have certain advantages, has great development potential and good application prospect.
In this paper, based on the idea of molecular design, with bivalent Cu, Co, Mn ions for the center, such as benzene tetracarboxylic acid, 1, 4 - double (imidazole - 1 -) butane (bbi), p-hydroxy benzoic acid as ligand, four new transition plexes were synthesized, and by X-ray single crystal diffraction, elemental analysis, IR, etc. To characterize the crystal structure.
Complexes 1: by X-ray single crystal diffraction, complexes 1 in two separate copper center, two bivalent copper center are distorted octahedral configurations. Benzene tetracarboxylic acid as bridging ligand separation through the carboxyl oxygen and adjacent Cu (1) the center coordination, the formation of one-dimensional infinite chain structure [Cu (C10H2O8) (C3H4N2) 2 (H2O) 2] n. And Cu (2) the central atom respectively with four imidazole and two water ligand form zero dimensional structure fragment Cu (C3N2H4) 2 (C2N3H3) 2 (H2O) 2.
Complexes 2: by IR, element analysis and thermogravimetric analysis, characteristic peak can be used to deduce plexes containing both p-hydroxy benzoic acid, and contains bbi, so you can determine plexes 2 is p-hydroxy benzoic acid and plexes.
Complexes 3: by IR, element ana
