摘要
The hydrothermal reaction of 1,2-dicyanobenzene with NaN3 in the presence of CuC12, 2,2＇-bipyridine and H2O affords a novel dinuclear copper（Ⅱ）-ditetrazolate, [Cu（bpy）- （pdtz）]2 （Hpdtz = 5,5＂-1,2-phenylene-ditetrazole, bpy = 2,2＇-bipyridine）. The pdtz ligand is generated in situ through Sharpless 2＋3 cycloaddition reaction. Its crystal structure was determined by single-crystal X-ray diffraction method. The crystal crystallizes in the monoclinic system, space group P211n with a = 8.2096（16）, b = 18.580（4）, c = 11.838（2） A, β = 103.12（3）°, V = 1758.5（6） A^3, Z = 2, Mr = 863.83, Dc = 1.631 g/cm^3, F（000） = 876 and μ = 1.272 mm^-1. In this novel dinuclear structure, the pdtz ligand adopts a peculiar μ2-η1,η2 coordination mode.
