摘　　要：利用二苄基二氯化锡和N, N-二甲基氨荒酸钠反应, 合成了二苄基锡N, N-二甲基氨荒酸酯(C20H26N2S4Sn, Mr = 541.36)。通过元素分析、红外光谱、核磁共振氢谱和质谱对其结构进行了表征。用X-射线单晶衍射测定了该化合物的晶体结构。化合物为单斜晶系, 空间群P21/n, a = 1.3926(5), b = 0.9832(4), c = 1.7080(7) nm, b = 103.541(6), V = 2.274(2) nm3, Z = 4, Dc = 1.581 g/cm3, m(MoKa) = 1.500 mm-1, F(000) = 1096, R = 0.0482, wR = 0.1162. 在化合物的晶体中, 锡原子为六配位的畸变八面体构型。Dibenzyltin N,N-dimethyldithiocarbamate was synthesized by the reaction of dibenzyltin dichloride with N,N-dimethyldithiocarbamate. The structure was characterized by elementary analysis, IR, H-1 NMR and NIS and the crystal structure was determined by X-ray single-crystal diffraction. The crystal belongs to monoclinic, space group P2(1)/n with a = 1.3926(5), b = 0.9832(4), c = 1.7080(7) nm, beta = 103.541(6)degrees, Z = 4, V = 2.2737(15) nm(3), D-c = 1.581 g/cm(3), mu(MoKalpha) = 1.500 mm(-1), F(000) = 1096, R = 0.0482 and wR = 0.1162. In the crystal of the title compound, the structures consist of discrete molecules containing six-coordinate tin atoms in a distorted octahedron configuration.
