The title complex, Cu(C(7)H(3)NO(4))(H(2)O)(2), was prepared under hydro-thermal reaction conditions. In the crystal structure, the Cu(II) cation is located on a twofold rotation axis and is coordinated by two carboxyl-ate O atoms and one N atom from three pyridine-3,5-dicarboxyl-ate (PDA) anions and two water mol-ecules with a distorted trigonal-bipyramidal geometry. The tridentate PDA anion is also located on the twofold rotation axis and bridges the Cu(II) cations to form a two-dimensional polymeric layer. O-H⋯O hydrogen bonding between layers links the two-dimensional layers into a three-dimensional supra-molecular framework.
标题配合物[Cu(C₇H₃NO₄)(H₂O)₂]ₙ是在水热反应条件下制备的。在晶体结构中，Cu(II)阳离子位于二重旋转轴上，由来自三个吡啶-3,5-二羧酸根（PDA）阴离子的两个羧酸根O原子和一个N原子以及两个水分子配位，形成扭曲的三角双锥几何构型。三齿PDA阴离子也位于二重旋转轴上，桥连Cu(II)阳离子形成二维聚合物层。层间的O-H⋯O氢键将二维层连接成三维超分子骨架。
