摘　　要：IMG SRC="IMAGE/11170016.JPG" HEIGHT=11 WIDTH=12> Tri(o chlorbenzyl)tin dithiotetrahydropyrrolocarbamate 1 and tri(o fluorbenzyl)tin dithiotetrahydropyrrolocarbamate 2 were synthesized. Their structures were characterized by elementary analysis, IR and 1H NMR and the crystal structures were determined by X ray single crystal diffraction. The crystal 1 belongs to triclinic with space group , a=0.9076(4)nm, b=1.0663(5)nm, c=1.5193(7)nm, α =75.811(6)° ,β =89.344(6)° , γ =72.665(6)° , Z=2, V=1.3577(11)nm3, Dc=1.569g· cm- 3, μ =1.406mm- 1, F(000)=644, R=0.0282, wR=0.0617.
