catena-Poly[[aqua­[1,4-bis­(1H-imidazol-4-yl)benzene]cadmium]-μ(3)-5-methyl­isophthalato]

In the title coordination polymer, [Cd(C(9)H(6)O(4))(C(12)H(10)N(4))(H(2)O)](n), the Cd(II) atom has a NO(6) donor set and is coord­inated by five carboxyl­ate O atoms from three different 5-methyl-1,3-phenyl­enediacetate (pda(2−)) anions, one O atom from a water mol­ecule and one N atom from a 1,4-bis­(1H-imidazol-4-yl)benzene (L) ligand, displaying a highly distorted penta­gonal–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 mol­ecules are linked through N—H⋯N and N—H⋯O hydrogen bonds into a three-dimensional network.
