Tetra(p-chlorobenzyl)tin(p-Cl-PhCH2)4Sn has been synthesized by the reaction of p-Cl-PhCH2 Cl with Sn. The crystal structure has been determined by X-ray single crystal diffraction. A crystal of the compound is or-thorhombic with space group fdd2,a=2. 1237(9)nm, 6=2. 2127(ll)nm, c=1.1235(5),a=90°,β=90°,γ= 90°,Z=8, V=5. 279(4)nm3, Dc=1. 562g/cm3,μ= 1. 388 mm-1, R = 0. 0396,wR=0. 0690. The tin atom has distorted tetrahedral configuration. The molecules are packed in the unit cell in one-dimensional chain structure through a weak interaction between the chlorine atom and another chlorine atom of an adjacent molecule.
