Low-temperature redetermination of tribenzyl­chloridotin(IV)

Abstract

Compared to the previous studies [Ng (1997 ▶). Acta Cryst. C 53, 56–58; Yin et al. (2005 ▶). Huaxue Shiji, 27, 295–296], the redetermined structure of the title compound, [Sn(C ₇H ₇) ₃Cl], exhibits a doubled c unit-cell parameter. There are two mol­ecules in the asymmetric unit, with both Sn and both Cl atoms having 3 site symmetry. The Sn atoms have distorted SnClC ₃ tetra­hedral geometries and the mol­ecules inter­act by way of short Sn⋯Cl bridges [Sn⋯Cl = 3.418 (2) and 3.475 (2) Å], thereby forming chains propagating in c.
