Abstract:

In the title salt, [(CH3CH2CH2)2NH2]4[Sn(C2O4)4]·H2O, the Sn(IV) atom of the stannate anion is located on a special position with -42m symmetry. It is eight-coordinated by four chelating oxalate anions. The di-propyl-ammonium cation possesses mirror symmetry while the lattice water mol-ecule is disordered about a position with -42m symmetry and has an occupancy of 0.25. In the crystal, the anions and cations are linked by N-H⋯O hydrogen bonds, forming a three-dimensional network. This network is futher stabilized by weak O-H⋯O hydrogen bonds involving the water mol-ecules and oxalate O atoms. The crystal studied was refined as an inversion twin.
