A polynuclear complex [Cd(endc)(H2O)]n·nH2O (endc = endo-norbornene-cis-5,6-dicarboxylate anion) has been synthesized by the hydrothermal reaction of cadmium nitrate tetrahydrate with endo-norbornene-cis-5,6-dicarboxylic acid in 1:1 molar ratio, and structurally characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 1.16471(7), b = 0.95334(7), c = 0.91109(9) nm, Z = 4, V = 1.01035(14) nm3, Dc = 2.160 g/cm3, μ = 2.172 mm-1, F(000) = 648, R = 0.0302 and wR = 0.0752. According to structural analysis, each Cd(Ⅱ) ion is coordinated to six O atoms from three endc anions and one water molecule, giving a distorted octahedral geometry. Two-dimensional layer arrangement of the title complex is constructed from the bridging nature of endc. It is worth notice that adjacent two-dimensional layers are joined together to form a three-dimensional supramolecular framework via intermolecular hydrogen bonding interactions.

Two-dimensional layer arrangement of the title complex is constructed from the bridging nature of endc. It is worth notice that an adjacent two-dimensional layers are joined together to form a three-dimensional supramolecular framework via intermolecular hydrogen bonding interactions.
