New oxalato and hydrogenoxalato organotin (IV) derivatives containing mono- and bichelating oxalates or a monochelating hydrogenoxalate, have been synthesized and characterized by elemental analyses, infrared and Mossbauer spectroscopy. The suggested structures are discrete, the environments around the tin (IV) atoms being trans octahedral, seven coordinated or tetrahedral. The cations when present are involved in NH…O bonds. A 1 D supramolecular architecture is suggested for SnPh2 (HC2O4)2.1/2 C6H6. The C6H6 molecules obtained in situ molecules are lattice. SnPh3OH is involved in hydrogen bonding.
