【摘要】 A novel 3D hetero-nuclear framework,namely [K2Cd5(Hbptc)4(H2O)12·12H2O]n(1,H4 bptc = biphenyl-2,3,3?,5?-tetracarboxylic acid),was obtained by hydrothermal reaction. X-ray singlecrystal structure analysis reveals that polymer 1 crystallizes in orthorhombic,space group Pbcn with a = 26.6152(13),b = 11.7449(5),c = 29.5923(14) ?,V = 9250.3(7) ?3,C64H76Cd5K2O56,Mr = 2381.44,Dc = 1.710 g/cm3,μ(MoK α) = 1.323 mm-1,F(000) = 4744,Z = 4,the final R = 0.0668 and wR = 0.1135 for 10613 observed reflections(I > 2σ(I)). Polymer 1 displays a 3D network that is built on the unprecedented heterobimetallic [Cd3Cd2K] molecular building block with a(3,4)-connected(6·8·8)2(6·6·82·82·126·126) topology which represents a rare 2-fold interpenetrating 3D framework topology network. The luminescence analyses reveal that polymer 1 shows obvious emission at room temperature in the solid state. In addition,it was also characterized by elemental,IR spectra and TG analyses.
