title: Tetra-methyl-ammonium aqua-trichlorido-oxalatostannate(IV) monohydrate.
abstract: The Sn(IV) atom in the title compound, [(CH(3))(4)N][Sn(C(2)O(4))Cl(3)(H(2)O)]·H(2)O, obtained from the reaction between SnCl(4) and [(CH(3))(4)N](2)C(2)O(4)·2H(2)O, is six-coordinated by three Cl atoms, an O atom of a water mol-ecule and two O atoms from an asymmetrically chelating oxalate anion. The environment around the Sn(IV) atom is distorted octa-hedral. The anions are connected by the lattice water mol-ecule through O-H⋯O hydrogen bonds, leading to a layered structure parallel to (010). The cations are located between these layers and besides Coulombic forces are connected to the anionic layers through weak C-H⋯O and C-H⋯Cl inter-actions.
