O用X射线衍射法测定了联苯甲酰-双-(缩氨基硫脲)合铜(Ⅱ)(以下简称CuL)的晶体及分子结构。该晶体属三斜晶系,P_1~-空间群,α=8.9491(7),b=9.595(1),c=10.882(1),α=99.42(1),β=106.19(1),γ=92.43(1)°,Z=2。R=0.025。 在CuL中,Cu(Ⅱ)由螫合环的N和S原子形成变形的平面四方型配位。分子之间未形成链式结构,这与Cu-KTS不同 O The crystal and molecular structure of dibenzoyl-bis- (thiosemicarbazone) copper (Ⅱ) (hereinafter referred to as CuL) were determined by X-ray diffraction. The crystal belongs to the triclinic system, the space group P_1 ~ -, α = 8.9491 (7), b = 9.595 (1), c = 10.882 (1), α = 99.42 = 92.43 (1) °, Z = 2. R = 0.025. In CuL, Cu (Ⅱ) forms a deformed planar tetragonal complex from the N and S atoms of the clathrated ring. There is no chain structure between molecules, which is different from Cu-KTS
