Two new coordination polymers, [Cd(N3)2(Baep)1/2]n(1) and [Cd2(N3)4(CH3OH)(Bapp)1/2]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), β=93.925(13)°, V=891.8(11)3 , Z=4, μ(MoKα)=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), α=72.91(2), β=77.10(2), γ=73.95(2)°, V=820.0(8)3 , Z=2, μ(MoKα)=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)4(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 {Cd4(N3)8(CH3OH)2(Bapp)}, in which the azido anions exhibit four different bridging modes (μ-1,1, μ-1,3, μ-1,1,1 and μ-1,1,3). The thermal stability and fluorescent property of 1 and 2 have also been investigated.
