A coordination polymer (CP) and a complex based on H(3)tbtd/H(3)bbta and bpy ligands, namely {[Co-3(tbtd)(2)(bpy)(2)(H2O)]center dot 5H(2)O}(n) (1) and [Cd-2(Hbbta)(bpy)(3)(C2O4)(H2O)] (2) (H(3)tbtd=4-(2,4,6-tricarboxylphenyl)-2,2',6',2 ''-terpyridine, H(3)bbta=1-fluoro-2,4,6-phenyltriacid, bpy=2,2'-dipvridine), have been hydrothermal synthesized and structurally characterized by elemental analyses, IR spectroscopy and single-crystal X-ray diffraction analyses. 1 shows 2D network structure, which is linked into 3D supramolecular network through intermolecular hydrogen bonding interactions. 2 is binuclear structure, which is linked by pi...pi stack interactions and hydrogen bonding interactions to firm 2D supramolecular network. CP 1 exhibited photocatalytic activities for degradation of methyl orange (MO) under UV light irradiai.ion and showed good stabilities toward UV-lighi. photocatalysis. In addition, luminescence property of 2 and thermal stabilities of 1 similar to 2 were also studied.
