Hexa-[mu]2-acetato-hexa-n-butylhexa-[mu]3-oxido-tin(IV) toluene monosolvate

M. Reichelt and H. Reuter

Abstract: 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.
