摘要 : Solvothermal reactions of Cu(NO3)(2)center dot 3H(2)O with trimesic acid (H3BTC) at different pH conditions yield two coordination polymers of [Cu-3(BTC)(2)(H2O)(3)(NH3)(4)](n)center dot 2nH(2)O (1) and [Cu-4(BTC)(2)(OH)(2)(H2O)(2... 展开 Solvothermal reactions of Cu(NO3)(2)center dot 3H(2)O with trimesic acid (H3BTC) at different pH conditions yield two coordination polymers of [Cu-3(BTC)(2)(H2O)(3)(NH3)(4)](n)center dot 2nH(2)O (1) and [Cu-4(BTC)(2)(OH)(2)(H2O)(2)(NH3)(4)](n) (2). Crystal structural analysis reveals that complex 1 exhibits a three-fold parallel interpenetration network and complex 2 shows a two-dimensional bilayer structure. Crystal data are orthorhombic, space group Pbcn, a = 11.242(3) angstrom, b = 16.963(4) angstrom, c = 13.898(4) angstrom, Z = 4 for 1 and monoclinic, space group C2/c, a = 18.887(4) angstrom, b = 10.761(2) angstrom, c = 14.488(3) angstrom, beta = 126.100(3)degrees, Z = 4 for 2. 收起
