A novel 3D hetero-nuclear framework, namely [K2Cd5(Hbptc)(4)(H2O)12 center dot 12H(2)O](n) (1, H(4)bptc = biphenyl-2,3,3',5'-tetracarboxylic acid), was obtained by hydrothermal reaction. X-ray single-crystal 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) angstrom, V = 9250.3(7) angstrom(3), C64H76Cd5K2O56, M-r = 2381.44, D-c = 1.710 g/cm(3), mu(MoKa) = 1.323 mm(-1), F(000) = 4744, Z = 4, the final R = 0.0668 and wR = 0.1135 for 10613 observed reflections (I > 2 sigma(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)(6.6.8(2).8(2).12(6).12(6)) 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.
