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. |
