[(i-Bu2NH2)2C2O4]4.SnPh2C2O4.C2O4(SnPh3)2 and [(i-Bu2NH2)2C2O4]3. SnBu2C2O4 have been synthesized and characterized by infrared and Mossbauer spectroscopies. The suggested structure are discrete (one being a two metallic components), the environments around the tin(IV) centres being octahedral and pentagonal bipyramidal, the oxalate anions being monodentate, the cations linking through N-H….O hydrogen bonds the free oxygen atoms of the oxalate. The second metallic component of one of the structures is cis coordinated C2O4(SnPh3)2.
