三邻氯苄基和三邻氟苄基锡吡咯烷氨荒酸酯的合成及晶体结构

Tri(o-chlorbenzyl)tin dithiotetrahydropyrrolocarbamate 1 and tri(o-fluorbenzyl)tin dithiotetrahydropyrrolocar-bamate 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， D_c=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， D_c=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.
