The SnIV atom in the title compound, [(CH3)4N][Sn(C2O4)Cl3(H2O)]·H2O, obtained from the reaction between SnCl4 and [(CH3)4N]2C2O4·2H2O, is six-coordinated by three Cl atoms, an O atom of a water molecule and two O atoms from an asymmetrically chelating oxalate anion. The environment around the SnIV atom is distorted octahedral. The anions are connected by the lattice water molecule through O—HO 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—HO and C—HCl interactions.
