Abstract

The title stannoxane is a toluene-solvated dimer, [Sn4(C7H6Cl)8Cl2O2(OH)2]·C7H8, the tetra­nuclear mol­ecule lying across a center of inversion. The Sn4O4 framework, whose two independent Sn atoms show trigonal bipyramidal coordination, is essentially planar (r.m.s deviation = 0.02 Å). One of the two chloro­benzyl groups of the chloridodiorganyltin unit is disordered over two positions with the chloro­phenyl residue refined over two positions in a 50:50 ratio. The solvent mol­ecule is disordered about a twofold axis.

Partial Text

The distannoxane is a hydrolysed product of di(4-chloro­benz­yl)dichloridotin(IV); for the synthesis of the organotin compound by the direct reaction of 4-chloro­benzyl chloride and metallic tin, see: Shishido et al. (1961 ▶). For octa­benzyl­dichloridodi-μ2-hydroxo-di-μ3-oxo-tetra­tin, which crystallizes as a toluene disolvate, see: Mohamed et al. (2004 ▶). For octa­(4-methyl­benz­yl)dichloridodi-μ2-hydroxo-di-μ3-oxo-tetra­tin, see: Wang et al. (2007 ▶).
