Popis: | Two new coordination polymers, [Zn(H2btc)(4,4′-bpy)2] n (1) and {[Cd(H2btc) (terpy)] · H2O} n (2) (H4btc = biphenyl-2,2′,4,4′-tetracarboxylic acid, 4,4′-bpy = 4,4′-bipyridine, terpy = terpyridine), have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. Complexes 1 and 2 are 1-D chains linked through partially deprotonated H4btc. The adjacent 1-D chains of 1 are further formed into 2-D supramolecular architecture through inter-chain N–H···O hydrogen bonds. In contrast, due to a different auxiliary ligand, the 1-D chains of 2 are further extended into 3-D supramolecular framework through inter-chain O–H···O hydrogen bonds. Thermal stabilities and luminescence of 1 and 2 were also studied. |
