    Abstract:
    Colourless crystals of the title compound, [Cd(2)(C(7)H(4)IO(2))(4)(C(12)H(10)N(2))(H(2)O)(2)](n), were obtained by the self-assembly of Cd(NO(3))(2)·4H(2)O, 1,2-bis(pyridin-4-yl)ethene (bpe) and 4-iodobenzoic acid (4-IBA). Each Cd(II) atom is seven-coordinated in a pentagonal-bipyramidal coordination environment by four carboxylate O atoms from two different 4-IBA ligands, two O atoms from two water molecules and one N atom from a bpe ligand. The Cd(II) centres are bridged by the aqua molecules and bpe ligands, which lie across centres of inversion, to give a two-dimensional net. Topologically, taking the Cd(II) atoms as nodes and the μ-aqua and μ-bpe ligands as linkers, the two-dimensional structure can be simplified as a (6,3) network.
