title: Diacetatodi-tert-butyltin(IV).
abstract: The title compound, [Sn(C4H9)2(CH3COO)2], was synthesized in order to study the influence of large organic groups on the mol-ecular structure of diorganotin di-acetates. The title compound exhibits the same structure type as other diorganotin(IV) di-acetates characterized by an unsymmetrical bidentate bonding mode of the two acetate groups to tin. The influence of the t-butyl groups on this mol-ecular structure is expressed in two significant differences: tin-carbon bond lengths are much more longer than in the other di-acetates, as are the additional inter-actions of the acetate groups with the tin atom. Inter-molecular inter-actions are restricted to C-H⋯O ones similar to those in the other di-acetates, giving rise to a chain-like arrangement of the molecules with the tin atoms and acetate groups in the propagation plane.
