Bottom Line: Each Sn(IV) cation is five-coordinated by the three phenyl groups and two O atoms belonging to the chelating oxalate ligand; the coordination geometry is that of a distorted trigonal bipyramid.One of the phenyl groups of one anion is disordered over two sets of sites in a 0.69:0.31 ratio.The Flack parameter value of 0.44 (1) indicates racemic twinning.

ABSTRACT
The title compound, (C(14)H(16)N)[Sn(C(6)H(5))(3)(C(2)O(2))], was synthesised by allowing C(2)O(4)(Bz(2)NH(2))(2) (Bz = benzyl) to react with SnPh(3)Cl. The asymmetric unit is built up by four SnPh(3)C(2)O(4) anions and four Bz(2)NH(2) cations which are related by a pseudo-inversion centre. Each Sn(IV) cation is five-coordinated by the three phenyl groups and two O atoms belonging to the chelating oxalate ligand; the coordination geometry is that of a distorted trigonal bipyramid. Anions and cations are linked through N-H⋯O hydrogen bonds into a layer structure parallel to (001). Moreover, the anion-cation pairs are associated by two bifurcated N-H⋯O hydrogen bonds, generating pseudo-dimers. One of the phenyl groups of one anion is disordered over two sets of sites in a 0.69:0.31 ratio. The Flack parameter value of 0.44 (1) indicates racemic twinning.
