合成了2个配位聚合物{[Zn(ip)(Eim)_2]·H_2O}(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α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Zn~(2+)/Zn~+对的氧化还原是一个准可逆的过程.

Two Zn(Ⅱ)coordination polymers{[Zn(ip)(Eim)_2]·H_2O}(1)and Zn(ip)(Mim)_2(2)(where ip~(2-)=isophthalatedianion:Eim=1-ethyl-1H-imidazole;Mim=1-methyl-1H-imidazole),have been synthesized and characterized by Xray single crystal diffraetometry.Complexes 1 and 2 contain polymeric zigzag chains extended along a axis,and each Zn(Ⅱ)atom is tetrahedrally coordinated to two O atoms from different isophthalate ions and two N atoms from Eim or Mim.There are only van der Waals interactions between the chains in 2,while 1D Zigzag chains in 1 are connected to form a 3D network by O-H…O contacts.The electrochemical studies reveal that redoxes of Zn~(2+)/Zn~+ in the complexes 1 and 2 are quasi-reversible processes.CCDC:762257,1;762258,2.
