摘 要:IMG SRC=IMAGE/*** 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. The crystal 2 belongs to monoclinic with space group P21/c, a=1.355(2)nm, b=1.0143(16)nm, c=1.986(3)nm, β =109.94(2)° , Z=4, V=2.565(7)nm3, Dc=1.539g· cm- 3, μ =1.195mm- 1, F(000)=1200, R=0.0467, wR=0.0788. In the crystals of 1 and 2, the structures consist of discrete molecules containing five coordinate tin atom in a distorted trigonal bipyramidal configuration. CCDC: 1, 213679; 2, 213680.
