Four new d10 metal-organic coordination polymers, [Zn(L)(phen)(H2O)] (1), [Cd(L)(phen)] (2), [Zn(L)(bppdc)]·3H2O (3), and [Cd(L)(bppdc)]·3H2O (4) [L=2-carboxymethylsulfanyl nicotinic acid, phen=1,10-phenanthroline, bppdc=N;N`-bis(pyridin-3-yl)pyridine-2,6-dicarboxamide], have been obtained from hydrothermal reactions of zinc(II)=cadmium(II) nitrates with the semi-rigid N-= S-containing dicarboxylate L, and the two structurally disparate neutral N-donor ligands phen and bppdc. Single-crystal X-ray diffraction analysis has revealed that compound 1 is a one-dimensional (1- D) helical coordination polymer linked by ZnII atoms and L spacers. Compound 2 features a doublechain structure connected via binuclear CdII units and pairs of L linkers. Adjacent chains of 1 and 2 are packed into 3-D supramolecular networks by hydrogen bonds and p-p stacking interactions. Compounds 3 and 4 exhibit similar 2-D (4,4)-connected wave-like networks based on linear [M-L]n and zigzag [M-bppdc]n metal-organic chains (M=ZnII for 3 and CdII for 4). The effects of metal ions and N-donor ligands with different coordination characters are discussed. Moreover, the photoluminescence properties and photocatalytic activities of compounds 1 - 4 were investigated.
