Abstract: | The title cadmium(II) polymer, catena‐polybis(4‐aminopyridine‐κN)aquacadmium(II)]‐μ‐1,4‐phenylenediacetato‐κ4O,O′:O′′,O′′′] dihydrate], {Cd(C10H8O4)(C5H6N2)2(H2O)]·2H2O}n, comprises one‐dimensional wave‐like chains, in which the Cd atom is coordinated by 1,4‐phenylenediacetate and 4‐aminopyridine molecules. The 1,4‐phenylenediacetate ligands lie about inversion centres. Extensive hydrogen‐bonding interactions between the chains lead to a three‐dimensional structure. Free water molecules form chains in the structure. |
