Crystal structure of bis-(benzoato-κO)di-butyl-tin(IV), nBu2Sn(bzo)2.

ABSTRACT: The title compound, [Sn(C4H9)2(C6H5COO)2], was synthesized in order to study the inter-action between di-n-butyl-tin(IV) oxide and some carb-oxy-lic acids. Di-n-butyl-tin(IV) dibenzoate, nBu2Sn(obz)2, exhibits the same structural features as other diorganotin(IV) dibenzoates characterized by an unsymmetrical bidentate bonding mode [Δ(Sn-O) ≃ 0.4 Å] of the two benzoate groups to tin. In a first approximation, the coordination sphere at tin resulting from the two stronger bonded O atoms [2.1227 (17) and 2.1405 (16) Å] and the two α-C atoms of the n-butyl groups [2.125 (3) and 2.129 (2) Å] is compressed to a tetra-gonal disphenoid [〈(C-Sn-C) = 148.2 (1)° and 〈(O-Sn-O) = 82.01 (6)°]. This coordination sphere is expanded by the less strongly bonded two O atoms [2.507 (2) and 2.485 (2) Å] to a s
