catena-Poly[[aqua[1,4-bis(1H-imidazol4-yl)benzene]cadmium]-μ3-5-methylisophthalato]

In the title coordination polymer, [Cd(C9H6O4)(C12H10N4)(H2O)](n), the Cd-II atom has a NO6 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 mu(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 center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds into a three-dimensional network.
