摘要
Two novel compounds, {[Cd（nbdc）（bpp）（H2O）]·H2O}n 1 and {[Cd（nbdc）（dpds）-（H2O）]·H2O}n 2（H2nbdc = 4-nitro-1,2-benzenedicarboxylic acid, bpp = 1,3-bis（4-pyridyl）propane and dpds = 4,4ˊ-dipyridyldisulfide）, were solvothermally synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis（TGA）, fluorescent analysis and single-crystal X-ray diffraction. Complex 1 is of monoclinic system, space group P21/c with a = 14.4370（17）, b = 8.4090（10）, c = 19.168（2） , β = 104.5050（10）°, V = 2252.8（5） 3, Dc = 1.639 g/cm3, Mr = 555.81, Z = 4, F（000） = 1120, μ = 1.022 mm-1, the final R = 0.0269 and wR = 0.0599 for 16656 observed reflections with I 〉 2σ（I）. 2 is isostructural to 1 with a = 14.4175（11）, b = 8.4737（7）, c = 18.0120（14） , β = 106.7220（10）°, V = 2107.5（3）3, Dc = 1.821 g/cm3, Mr = 577.85, Z = 4, F（000） = 1152, μ = 1.287 mm-1, the final R = 0.0280 and wR = 0.0705 for 15136 observed reflections with I〉 2σ（I）. Both complexes present intimately related structures featuring infinite Cd-carboxylate helix of [CdⅡ（nbdc）（H2O）]n connected by bpp（or dpds） molecule to produce the 2D layer frameworks.
