Abstract
Compared to the previous studies [Ng (1997 ▶). Acta Cryst. C53, 56-58; Yin et al. (2005 ▶). Huaxue Shiji, 27, 295-296], the redetermined structure of the title compound, [Sn(C(7)H(7))(3)Cl], exhibits a doubled c unit-cell parameter. There are two mol-ecules in the asymmetric unit, with both Sn and both Cl atoms having 3 site symmetry. The Sn atoms have distorted SnClC(3) tetra-hedral geometries and the mol-ecules inter-act by way of short Sn⋯Cl bridges [Sn⋯Cl = 3.418 (2) and 3.475 (2) Å], thereby forming chains propagating in c.
