dc.description.abstractThe title compound, [Sn(C4H9)2(C6H5COO)2], was synthesized in order to study the interaction between di-n-butyltin(IV) oxide and some carboxylic acids. Di-nbutyltin( IV) dibenzoate, nBu2Sn(obz)2, exhibits the same structural features as other diorganotin(IV) dibenzoates characterized by an unsymmetrical bidentate bonding mode [delta(Sn—O) ’ 0.4 A ° ] 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) A ° ] and the two alpha-C atoms of the n-butyl groups [2.125 (3) and 2.129 (2) A ° ] is compressed to a tetragonal disphenoid [h(C—Sn—C) = 148.2 (1)° and h(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) A ° ] to a substantially distorted octahedron and by a weak intermolecular Sn...O interaction [2.943 (2) A ° ] to a pentagonal bipyramid with the formation of centrosymmetric dimers. The unbranched butyl groups adopt two different conformations: anti–gauche [torsion angles: 166.0 (2)–63.9 (4)°] and gauche–gauche [65.0 (3)–56.3 (3)°]. Intermolecular interactions between the dimers are restricted to O...H—C contacts (2.64 A ° ) and van der Waals interactions. 1.eng
