In the title complex, [Cd(C(7)H(4)N(5)O(2))(2)(H(2)O)(2)]·2H(2)O, the water-coordinated Cd(II) atom ( symmetry) is coordinated by four N atoms from two symmetry-related 3-carboxy-pyidyl-6-tetra-zolato ligands, forming a distorted octa-hedral complex. The uncoordinated water mol-ecules connect the mononuclear units into a layer structure through O-H⋯N and O-H⋯O hydrogen bonds; similar hydrogen bonds between coordinated water mol-ecules and anionic groups result in a three-dimensional structure.
在标题配合物[Cd(C₇H₄N₅O₂)₂(H₂O)₂]·2H₂O中，与水配位的Cd(II)原子（对称）由来自两个对称相关的3-羧基吡啶-6-四唑配体的四个N原子配位，形成一个扭曲的八面体配合物。未配位的水分子通过O—H⋯N和O—H⋯O氢键将单核单元连接成层状结构；配位水分子与阴离子基团之间类似的氢键形成三维结构。
