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.
