| Abstract | Two novel compounds, {[Cd(nbdc)(bpp)(H2O)]center dot H2O}(n) 1 and {[Cd(nbdc)(dpds)-(H2O)]center dot H2O}(n)2 2 (H(2)nbdc = 4-nitro-1,2-benzenedicarboxylic acid, bpp = 1,3-bis(4-pyridyl)propane and dpds = 4,4'-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 P2(1)/c with a = 14.4370(17), b = 8.4090(10), c = 19.168(2) A, beta = 104.5050(10)degrees, V = 2252.8(5) A(3), D-c = 1.639 g/cm(3), M-r = 555.81, Z = 4, F(000) = 1120, mu = 1.022 mm(-1), the final R = 0.0269 and wR = 0.0599 for 16656 observed reflections with I > 2 sigma(1). 2 is isostructural to 1 with,a = 14.4175(11), b = 8.4737(7), c = 18.0120(14) A, beta = 106.7220(10)degrees, V = 2107.5(3) A(3), D-c = 1.821 g/cm(3), M-r =577.85, Z = 4, F(000) = 1152, mu = 1.287 mm(-1), the final R = 0.0280 and wR = 0.0705 for 15136 observed reflections with I> 2 sigma(I). Both complexes present intimately related structures featuring infinite Cd-carboxylate helix of [Cd-II(nbdc)(H2O)](n) connected by bpp (or dpds) molecule to produce the 2D layer frameworks. |
