New Semiconducting Coordination Polymers from Zinc Sulfide Clusters and Chains ChenZiyi LuoDaibing KangMaoping LinZhien 2011 Two new semiconducting zinc coordination polymers, Zn<sub>8</sub>S(SPh)<sub>14</sub>(bpy) (<b>1</b>) and Zn<sub>2</sub>(SPh)<sub>4</sub>(bpy) (<b>2</b>), have been synthesized by a dual-ligand approach. Single-crystal structural analyses indicate that compound <b>1</b> has a helical-chain structure with P1 clusters bridging with bipyridyl (bpy) ligands and compound <b>2</b> possesses a layered structure with zinc sulfide chains cross-linked with bpy ligands. The diffuse-reflectance spectra reveal that the band gaps of the two compounds are 2.41 eV for <b>1</b> and 2.56 eV for <b>2</b>.
