Tri(p-fluorobenzyl)tin chloride (1) and tri(p-fluorobenzyl)tin N,N-(1,4-butylene)dithiocarbamate (2) were synthesized. Their structures were characterized by elemental analysis, IR and 1H NMR, and the crystal structures were determined by X-ray single crystal diffraction analysis. The crystal 1 belongs to monoclinic with space group P2 1, 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) nm 3, D c=1.608 g/cm 3, μ=1.447 mm -1, R 1=0.0397, wR 2=0.0813. The crystal 2 belongs to monoclinic with space group P2 1/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) nm 3, D c=1.537 g/cm 3, μ=1.197 mm -1, R 1=0.0363, wR 2=0.0796. In the crystals of 1, the tin atom rendered four-coordinate in a distorted tetrahedron structure. In the crystals of 2, the structures consist of discrete molecules containing five-coordinate tin atom in a distorted trigonal bipyramidal configuration.
