2-Amino-6-methyl­pyridinium trans-di­aqua­dioxalatochromate(III) monohydrate

In the title compound, (C₆H₉N₂)[Cr(C₂O₄)₂(H₂O)₂]·H₂O, the Cr^III atom adopts a slightly distorted octa­hedral coordination environment defined by two chelating oxalate ligands in the equatorial plane and two water mol­ecules in axial positions. A three-dimensional network is generated by inter­molecular N—H...O and O—H...O hydrogen-bonding interactions involving the cation, the complex anion and the lattice water molecule.
