Abstract: Tri(o-bromobenzyl)tin bromide was reacted with 1-pyrrolidinecarbodithioicacid sodium salt to synthesize tri(o-bromobenzyl)tin dithiotetrahydropyrrolocarbamate. The crystal structure of tri(o-bromobenzyl)tin dithiotetrahydropyrrolocarbamate was determined by X-ray diffraction. The compound crystallizes in triclinic space group P1 with cell parameters of a=0.91354(11) nm, b=1.07313(13) nm, c=1.52677(18) nm， α=75.440(6)°， β=89.499(6)°， γ=72.515(7)°， V=1.3781(3) nm3， Z=2， Dc=1.868 g/cm3，μ(MoKα)=54.43 cm-1， F(000)=752， R1=0.0320， wR2=0.0765. The tin atom of the compound has a distorted tetrahedral geometry. The stabilities, some frontier molecular orbital energies and composition characteristics of some frontier molecular orbital of the complex were also investigated. Furthermore, the anticancer activity of the complexes was tested.

Key words: tri(o-bromobenzyl)tin dithiotetrahydropyrrolocarbamate, synthesis, structure, antitumor activity
