摘　　要：利用二苄基二氯化锡和哌嗪单荒酸盐反应 ,合成了氯代二苄基锡哌嗪单荒酸酯 .通过元素分析、红外光谱和核磁共振氢谱对其结构进行了表征 ,并用X射线单晶衍射测定了晶体结构 .该化合物属于单斜晶系 ,空间群为P2 1 ,a =0 .6 36 35 (10 )nm ,b =1.6 16 7(3)nm ,c=0 .876 4 1(14 )nm ,β =95 .6 73(2 )° ,Z =2 ,V =1.0 5 94 (3)nm3,Dc=1.5 6 0g cm3,μ =1.5 34mm- 1 ,F(0 0 0 ) =5 0 0 ,R =0 .0 2 77,wR =0 .0 70 6 [I≥ 2σ(I) ].化合物中 ,锡原子呈五配位畸变三角双锥构型 .分子间通过S…S和S…Cl近距作用 ,形成一维链状结构 .Chlorodibenzyltin piperazinylmonodithiocarbamate was synthesized by the reaction of dibenzyltin dichloride with piperazinylmonodithiocarbamate and characterized by elemental analysis, IR and 1H NMR spectroscopy. The crystal structure was determined by X ray single crystal diffraction study. The crystallographic data are as follows: triclinic, space group P 2 1, a =0.63635(10) nm, b =1.6167(3) nm, c =0.87641(14) nm, β =95.673(2)°, Z =2, V =1.0594(3) nm 3, D c=1.560 g/cm 3, μ =1.534 mm -1 , F (000)=500, R =0.0277, wR =0.0706 [ I ≥2 σ ( I )]. The structure consists of discrete molecules containing five coordinate tin atoms in a seriously distorted trigonal bipyramidal configuration. The molecules are packed in the unit cell in one dimensional chain polymer through weak interactions between the chlorine and sulfur atoms and one of the sulfurs of an adjacent molecule.
