| Abstract: | Four novel coordination polymers, [Cd(Hdtbb)(dtbb)0.5(DMF)]n (1), {[Cd(dtbb)(2,2′-bpy)(H2O)]·2DMA}n (2), {[Cd2(dtbb)2(1,4-bix)2]·3DMF}n (3) and [Cd(dtbb)(1,4-btx)]n (4) [H2dtbb = 2,2-dithiobisbenzoic acid, 2,2′-bpy = 2,2′-bipyridine, 1,4-bix = 1,4-bis(imidazol-1-ylmethyl)benzene, 1,4-btx = 1,4-bis(triazol-1-ylmethyl)benzene] have been synthesized and structurally characterized. Complexes 1 and 2 possess one-dimensional (1D) infinite structures. The structures of complexes 3 and 4 exhibit two dimensional (2D) frameworks, which mainly due to the differences in the bridging modes of dtbb2− ligand and the effect of the N-donor auxiliary ligands. The infrared spectra, thermogravimetric and luminescent properties were also investigated for these compounds. |
