摘要
The title azide-bridged dinuclear Schiff base zinc（Ⅱ） complex [Zn2（C12H16N3O3）2- （μ1,1-N3）2] was prepared and characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/n with a = 8.736（2）, b = 14.850（3）, c = 11.775（2）A, β = 102.42（3）°, V = 1491.8（5） A^3, Z = 2, Dc = 1.593 g/cm^3, Mr = 715.36, λ（MoKα） = 0.71073A , μ = 1.669 mm^-1, F（000） = 736, the final R = 0.0338 and wR = 0.0789. A total of 3411 unique reflections were collected, of which 2777 with I 〉 2σ（I） were observed. The molecule of the complex is located on a crystallographic inversion centre. Each Zn atom in the complex is five-coordinated by one Schiff base ligand and two bridging azide groups, forming a trigonal bipyramidal configuration. The Zn···Zn distance is 3.328（2）A . In the crystal structure, molecules are linked through intermolecular C–H…N hydrogen bonds, forming layers parallel to the bc plane. The complex shows low cytotoxic property to both normal and carcinoma cells.
