Tri(p-fluorobenzyl)tin chloride (1) and tri(p-fluorobenzyl)tin dithiotetrahydropyrrolocarbamate (2) were synthesized. Their structures were characterizedby elemental analysis, IR and 1H NMR, and the crystal structures were determinedby X-ray single crystal diffraction analysis. The crystal 1 belongs to monoclinic with space group P21, a=0.8403(3) nm, b=0.5958(2) nm, c=2.0016(8)nm, β=97.052(6)°, Z=2, V=0.9945(7) nm3, Dc=1.608 g/cm3, μ=1.447 mm-1, R1=0.0397, wR2=0.0813. The crystal 2 belongs to monoclinic with space group P21/n, a=0.8786(9) nm, b=1.993(2) nm, c=1.5039(15) nm, β=103.548(15)°, Z=4. V=2.560(4) nm3, Dc=1.537 g/cm3, μ=1.197 mm-1, R1=0.0363, wR2=0.0796. In the crystals of 1, the tin atom rendered four-coordinate ina distorted tetrahedron structure. In the crystals of 2, the structures consistof discrete molecules containing five-coordinate tin atom in a distorted trigonal bipyramidal configuration.
