Hexa-μ₂-acetato-hexa-n-butyl­hexa-μ₃-oxido-tin(IV) toluene monosolvate

The title compound, [Sn₆(C₄H₉)₆(CH₃COO)₆O₆]·C₇H₈, has one half-toluene mol­ecule and one half-organotin mol­ecule in the asymmetric unit. The latter is situated about an inversion centre and belongs to the class of hexa­meric monoorganooxo­tin carboxyl­ates with a hexa­gonal prismatic or `drum-like' motif of the central tin–oxygen core. Two Sn₃O₃ rings in a flat-chair conformation are linked via six Sn—O bonds and six bridging acetate groups. All Sn atoms have approximate octa­hedral coordination geometry. The Sn—O bonds which are trans to the alkyl group are significantly shorter than the others. One butyl group is disordered over two different sites, with occupancies of 0.9:0.1. Very large atomic displacement parameters of the toluene mol­ecule indicate an unresolvable disorder about the twofold axis.
