Structural characterization of a binuclear tin adduct: µ-oxalato-bis[nitratodiphenyl(triphenylarsine oxide)tin(IV)]

Abstract

The crystal structure of the title compound [SnPh₂(NO₃)(AsPh₃O)]₂(C₂O₄) has been determined by X-ray diffraction. The co-ordination geometry of the tin atom is a slightly distorted pentagonal bipyramid, the two phenyl rings occupying the axial positions, with the nitrate and oxalate ions and the triphenylarsine oxide in the equatorial plane. The compound exhibits a binuclear structure with the oxalate ion acting as centrosymmetric bridge between two co-ordination polyhedra.
