摘要
Four novel coordination polymers, [Cd(Hdtbb)(dtbb)(0.5)(DMF)](n) (1), {[Cd(dtbb)(2,2'-bpy)(H2O)]center dot 2DMA}(n) (2), {[Cd-2(dtbb)(2)(1,4-bix)(2)]center dot 3DMF}(n) (3) and [Cd(dtbb)(1,4-btx)](n) (4) [H(2)dtbb = 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-yl-methyl)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 dtbb(2) ligand and the effect of the N-donor auxiliary ligands. The infrared spectra, thermogravimetric and luminescent properties were also investigated for these compounds. (C) 2011 Elsevier B. V. All rights reserved.
