The title compound, {[Cu(C(12)H(6)N(2)O(4))(H(2)O)(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The Cu(2+) ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2'-bipyridine-3,3'-dicarboxyl-ate bridging ligand in a sligthly distorted octa-hedral environment. The 2,2-bipyridine-3,3'-dicarboxyl-ate bridges link the Cu(2+) ions into chains along the b-axis direction. These chains are further linked by O-H⋯O hydrogen bonds involving the water solvent mol-ecules, forming a three-dimensional framework.
标题化合物{[Cu(C₁₂H₆N₂O₄)(H₂O)₃]·H₂O}ₙ是在水热条件下合成的。Cu²⁺离子由三个水分子的O原子、2,2'-联吡啶-3,3'-二羧酸桥联配体的两个N原子和一个O原子在略微扭曲的八面体环境中六配位。2,2-联吡啶-3,3'-二羧酸桥将Cu²⁺离子沿b轴方向连接成链。这些链通过涉及水溶剂分子的O-H⋯O氢键进一步连接，形成三维框架。
