In the title coordination polymer, Cd(C(9)H(6)O(4))(C(12)H(10)N(4))(H(2)O), the Cd(II) atom has a NO(6) donor set and is coord-inated by five carboxyl-ate O atoms from three different 5-methyl-1,3-phenyl-enediacetate (pda(2-)) anions, one O atom from a water mol-ecule and one N atom from a 1,4-bis-(1H-imidazol-4-yl)benzene (L) ligand, displaying a highly distorted penta-gonal-bipyramidal geometry. Each pda(2-) anion acts as a μ(3)-bridge, linking Cd(II) atoms to form one-dimensional slabs extending parallel to [010]. In the crystal, adjacent mol-ecules are linked through N-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.
在标题配位聚合物[Cd(C₉H₆O₄)(C₁₂H₁₀N₄)(H₂O)]ₙ中，Cd(II)原子具有一个NO₆供体集，由来自三个不同的5-甲基-1,3-苯二甲酸根（pda²⁻）阴离子的五个羧酸根O原子、一个水分子的O原子和一个1,4-双（1H-咪唑-4-基）苯（L）配体的N原子配位，呈现出高度扭曲的五角双锥几何构型。每个pda²⁻阴离子作为一个μ₃-桥，连接Cd(II)原子形成平行于[010]延伸的一维平板。在晶体中，相邻分子通过N-H⋯N和N-H⋯O氢键连接成三维网络。
