摘要

Cu(II) and Pb(II) complexes of 4,4'-bipyridine-N,N'-dioxide have been prepared using a solvent-layering system. [Cu2Cl4(bpdo)(3)(H2O)(2)] . 2(CH3)(2)SO (1) crystallises in P-1, a=8.731(2), b=8.943(2), c=14.408(3) angstrom, alpha=102.85(3), beta=97.49(3), gamma=109.77(3)degrees. The Cu(II) complex is a z-shaped discrete molecule with a DMSO molecule hydrogen bonded to the host through coordinated water molecule. Crystallisation of PbCl2, PbBr2 and PbI2 with bpdo afforded isostructural 2D coordination polymers. [PbCl2(bpdo)](n) is monoclinic, C2/c with a=16.3274(7), b=4.0708(1), c=18.6146(8) angstrom, beta=93.73(1)degrees; [PbBr2(bpdo)](n) is monoclinic, C2/c with a=16.403(3), b=4.2412(8), c=18.846(4) angstrom, beta=92.59(3)degrees and [PbI2(bpdo)](n) is monoclinic, C2/c with a=16.438(3), b=4.538(1), c=18.973(4) angstrom, beta=91.04(3)degrees. The adjacent metal centres of these polymers are bridged by coordinated Cl-, Br- or I- anions as well as by bpdo ligands. These polymers possess no conventional hydrogen bonds.
