| Two Zn(Ⅱ) Coordination Polymers Based on Isophthalate and Imidazole Derivatives: Synthesis, Crystal Structures, and Electrochemical Properties |
|
| 摘要: 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。 |

| Abstract: Two Zn(Ⅱ) coordination polymers {[Zn(ip)(Eim)2]·H2O} (1) and Zn(ip)(Mim)2 (2) (where ip2-=isophthalate dianion; Eim=1-ethyl-1H-imidazole; Mim=1-methyl-1H-imidazole), have been synthesized and characterized by X-ray single crystal diffractometry. 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 Zn2+/Zn+ in the complexes 1 and 2 are quasi-reversible processes. CCDC: 762257, 1; 762258, 2. |
