摘要

Two new coordination polymers, [Cd(N3)2(Baep)l/2]n (1) and [Cd2(N3)4(CH3OH)(Bapp)I/.2]n (2) (Baep = 1,4-bis(2-aminoethyl)piperazine, Bapp = 1,4-bis(3-aminopropyl)piperazine) were synthesized. The crystal of 1 is of monoclinic system, space group P21/c with a = 9.341(7), b = 11.677(9), c = 8.195(6) A, fl = 93.925(13), V= 891.8(11) A3, Z= 4, μ(MoKa) = 2.42 mm-1, Mr = 280.58, Dc = 2.090 g/cm3, the final R = 0.0297 and wR = 0.0720. The crystal of 2 is of triclinic system, space group PI with a = 9.121(5), b = 9.666(5), c = 10.250(6) A, a = 72.91(2), β= 77.10(2), V = 73.95(2)°, V = 820.0(8)°, Z = 2,μ(MoKa) = 2.62 mm-1, Mr= 522.10, Dc = 2.114 g/cm3, the final R = 0.0251 and wR = 0.0632. Single-crystal X-ray diffraction studies reveal that 1 is a 3D structure based on a dinuclear unit {Cd2(N3)a(Baep)}, in which the Baep ligands formed in situ display two different bridging modes. Compound 2 also has a 3D structure based on a tetranuclear cluster {Cda(N3)8(CH3OH)2(Bapp)}, in which the azido anions exhibit four different bridging modes (μ-1,1, μ-1,3, μ-l,l,1 and μ-1,1,3). The thermal stability and fluorescent property of 1 and 2 have also been investigated.
