具有Zigzag链结构的二维甲酸铜配位聚合物[Cu(COOH)_2·HCOOH]的合成及晶体结构

Synthesis and Crystal Structure of a Two-dimensional Copper(Ⅱ) Formate Complex [Cu(COOH)_2·HCOOH] with Zigzag Chain

利用溶剂热脱水法合成了新型无水甲酸铜配位聚合物[Cu(COOH)_2·HCOOH].通过X-射线单晶衍射、元素分析、红外(IR)对其进行表征.结果表明[Cu(COOH)_2·HCOOH]晶体属正交晶系,Pbca空间群.晶体结构中有一个晶体学独立的铜原子,其与来自4个甲酸配体的4个氧原子配位,形成了一维Zigzag链,链与链间又互相连接形成了波浪状的二维层状结构.

A novel anhydrous copper formate coordination polymer Cu( COOH)_2· HCOOH has been successfully synthesized under solvothermal condition.The compound was characterized by singal-crystal X-ray analysis,elemental analysis and infrared( IR) spectroscopy.Single crystal X-ray analysis reveals that the copper formate crystallizes in Orthorhombic with space group Pbca. In the crystal structure,there is only one unique copper atom that is coordinated with four oxygen atoms of four formate ligands forming a Zigzag chain.And all these Zigzag chain are linked each other by formate bridges complting wave like 2D layered framework.
