The title compound [n-Pr2NH2]2[(C2O4)2SnPh2] (1) has been synthesized by allowing Ph2SnCl2 to react with [n-Pr2NH2]2C2O4. In 1, characterized using X-ray crystallography, the Sn atom is six-coordinated by two phenyl groups and four oxygen atoms belonging to two asymmetrically chelating oxalate ligands. The geometry is cis octahedral about tin. In the structure of 1, there are two [(C2O4)2SnPh2]2- moieties differentiated by their ∠C-Sn-C angles [105.07° (15°) and 107.43° (16°)]. These similar, but distinct, anions are connected by [n-Pr2NH2]+ cations through N-H···O hydrogen bonds leading to two infinite alternating chains (1) and (2), which loosely assemble via π-π stacking between phenyl groups of adjacent molecules to generate an overall layered structure.
