Abstract
Two new compounds, [Cd2(bptc)(bpimb)(H2O)] · 2H2O (1) and [Cd2(bptc)(bpib)] · 4H2O (2) (where H4bptc = biphenyl-3,3′,4,4′-tetracarboxylic acid, bpimb = 1,3-bis((2-(pyridin-2-yl)-1H-imidazol-1-yl)methyl)benzene, bpib = 1,4-bis(2-(pyridin-2-yl)-1H-imidazol-1-yl)butane), were synthesized by reactions of the corresponding metal salts with H4bptc and N-containing auxiliary ligands and their structures have been determined by single-crystal X-ray diffraction. Compound 1 is built by Cd4-clusters which further construct a 3-D (3,8)-connected framework with tfz-d notation; 2, also built by Cd4-clusters, is a 3-D (4,8)-connected framework with (32 · 42 · 52)(34 · 48 · 512 · 64) topology. In addition, the elemental analyses, infrared spectra, fluorescence, and thermogravimetric analyses for 1 and 2 are discussed.
