| 摘 要： | The complex Cd（H2mbdpz）（N3）2]n 1 （H2mbdpz = 4,4′-methylenebis（3,5-dimethylpyrazole）） has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis. It crystallizes in the monoclinic system, space groups C2/c with a = 22.154（5）, b = 7.4835（15）, c = 21.044（8）A^°,β= 115.51（3）°, V= 3148.7（17）A^°3, Z= 8, C11H16CdN10, Mr = 400.75, Dc = 1.691 g/cm^3,μ = 1.401 mm^-1, F（000） = 1599, T= 293（2） K, the final R = 0.0228 and wR = 0.0581 for 3604 observed reflections with I 〉 2σ（I）. The structural determination revealed that the coordination environment of Cd（Ⅱ） atom is a distorted octahedron consisting of two nitrogen donors of two H2mbdpz ligands and four nitrogen donors from four azide ligands. The azide moieties act as bridges in two modes： end-on （μ1,1-） and end-to-end （μ1,3-）, and H2mbdpz also serves as a bridge with a bis-monodentate coordination. Both bridging ligands link the Cd（Ⅱ） atoms to form a distorted two-dimensional （6,3） layer.

| Abstract: | The complex Cd(H_2mbdpz)(N_3)_2]_n 1 (H_2mbdpz=4,4'-methylenebis(3,5-dimethylpyrazole)) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis. It crystallizes in the monoclinic system,space groups C2/c with α=22.154(5),b= 7.4835(15),c=21.044(8)(A),β =115.51(3)°,V=3148.7(17)(A)3,Z=8,C_(11)H_(16)CdN_(10),M_r=400.75,D_c =1.691 g/cm~3,μ=1.401 mm~(-1),F(000)=1599,T=293(2) K,the final R=0.0228 and wR =0.0581 for 3604 observed reflections with Ⅰ > 2σ(Ⅰ). The structural determination revealed that the coordination environment of Cd(Ⅱ) atom is a distorted octahedron consisting of two nitrogen donors of two H2mbdpz ligands and four nitrogen donors from four azide ligands. The azide moieties act as bridges in two modes: end-on (μ1,1~-) and end-to-end(μ1,3~-),and H_2mbdpz also serves as a bridge with a bis-monodentate coordination. Both bridging ligands link the Cd(Ⅱ) atoms to form a distorted two-dimensional (6,3) layer. |
