合成了2个配位聚合物{[Zn(ip)(Eim)2]·H2O}(1)和Zn(ip)(Mim)2(2)(ip为间苯苯二甲酸阴离子,Eim为1-乙基咪唑,Mim为1-甲基咪唑),并用X射线单晶衍射仪测定了其晶体结构。2个配合物的结构中都含有沿晶体a轴方向的zigzag聚合链,每个Zn原子分别与2个来自不同间苯二甲酸离子氧原子和2个来自乙基咪唑或甲基咪唑的N原子配位,形成了配位四面体。在配合聚合物2中各链间只存在范德法力相互作用,而在配合物1中一维链通过O-H…O氢键相互作用进一步连接形成了三维网络结构。电化学研究表明在配合物1和2中Zn2+/Zn+对的氧化还原是一个准可逆的过程。
Two complexes of {Zn (ip) (Eim) 2] · H2O} (1) and Zn (ip) (Mim) 2 (2) were synthesized with ip being an isophthalic acid anion and Eim being 1 - ethyl imidazole, Mim is 1-methylimidazole), and its crystal structure was determined by X-ray single crystal diffractometer. The two complexes all contain zigzag polymeric chains along the a-axis of the crystal. Each Zn atom is bound to two N atoms from different isophthalic ion oxygen atoms and two from ethylimidazole or methylimidazole Coordination, formed a coordination tetrahedron. There was only van der Waals interactions between the various chains in the complex 2, while the one-dimensional chain in the complex 1 was further connected by the O-H ... O hydrogen bond interaction to form a three-dimensional network structure. Electrochemical studies show that the redox couple of Zn2 + / Zn + complexes in complexes 1 and 2 is a quasi-reversible process.
