摘要
A novel copper(II) coordination polymer, poly[[[ aquacopper( II)]-mu(3)-2,2';-bipyridyl- 3,3';-dicarboxylato-kappa(4) N, N';: O:O';] dihydrate], {[Cu(C12H6N2O4)(H2O)] . 2H(2)O}(n), was obtained by the reaction of CuCl2 . 2H(2)O and 2,2';-bipyridyl- 3,3';-dicarboxylic acid (H2L) in water. In the molecule, each Cu-II atom is five-coordinated and lies at the centre of a square-pyramidal basal plane, bridged by three L ligands to form a two-dimensional ( 4,4)-network. Each L moiety acts as a bridging tetradentate ligand, coordinating to three Cu-II atoms through its two aromatic N atoms and two O atoms of the two carboxyl groups. The two-dimensional square-grid sheets superimpose in an off-set fashion through the inorganic water layer.
