Abstract

In the title compound, [Cu(2)Cl(2)(NO(3))(2)(C(12)H(8)N(2)O(4))(2)(H(2)O)(2)], which consists of a chloride-bridged Cu(II) dimer, the Cu atom is in a distorted octa-hedral environment defined by two N atoms from the 2,2'-bipyridine-4,4'-dicarboxylic acid ligand (H(2)bpdca), two bridging chlorido ligands, and two O atoms from an equatorial water mol-ecule and an axial nitrate anion, respectively. The two halves of the dimeric unit are related by an inversion centre at the midpoint between the two Cu atoms. Both carboxylic acid groups in the H(2)bpdca ligand remain protonated, as confirmed by the two sets of C-O bond lengths. The dinuclear mol-ecules are linked into a three-dimensional network via inter-molecular hydrogen bonds.

摘要

在标题化合物[Cu₂Cl₂(NO₃)₂(C₁₂H₈N₂O₄)₂(H₂O)₂]中，它由一个氯桥联的Cu(II)二聚体组成，Cu原子处于一个扭曲的八面体环境中，该环境由来自2,2'-联吡啶-4,4'-二羧酸配体（H₂bpdca）的两个N原子、两个桥联氯配体以及分别来自一个赤道面水分子和一个轴向硝酸根阴离子的两个O原子定义。二聚体单元的两半通过两个Cu原子之间中点处的一个对称中心相关联。H₂bpdca配体中的两个羧酸基团均保持质子化状态，这由两组C - O键长得到证实。双核分子通过分子间氢键连接成三维网络。
