In the title compound, [Cd(C8H4N8)(H2O)4] n , 5,5'-(1,4-phenyl-ene)di(tetra-zol-2-ide) (L) ligands bridge Cd(II) atoms into polymeric chains along [201]. The Cd(II) atom is situated on an inversion centre and is coordinated by two N atoms from two L ligands and by four water O atoms in a distorted octa-hedral geometry. In the L ligand, the benzene ring resides on an inversion centre and the tetra-zole rings are twisted from its plane by 22.3 (1)°. An extensive hydrogen-bonding network formed by classical O-H⋯N and O-H⋯O inter-actions consolidates the crystal packing, linking the poymeric chains into a three-dimensional structure.
在标题化合物[Cd(C₈H₄N₈)(H₂O)₄]ₙ中，5,5'-(1,4-亚苯基)二(四唑-2-基)（L）配体将Cd(II)原子沿[201]方向桥连形成聚合物链。Cd(II)原子位于一个对称中心上，由来自两个L配体的两个N原子和四个水分子的O原子配位，呈扭曲的八面体几何构型。在L配体中，苯环位于一个对称中心上，四唑环与苯环平面扭转了22.3 (1)°。由经典的O—H⋯N和O—H⋯O相互作用形成的广泛氢键网络巩固了晶体堆积，将聚合物链连接成三维结构。
