Abstract: In the crystal structure of the title compound, [Co(C₇H₇N₂O₄)(H₂O)₄]Cl(OH)·2H₂O, the cations form a polycationic chain that propagates along the b axis of the monoclinic unit cell. The Co^III atom and two coordinated water molecules lie on special positions of site symmetry m. The C₇H₇N₂O₄ anion displays crystallographic mirror symmetry. The chloride and hydroxide anions are disordered and they interact, along with the uncoordinated water molecule, with the polycationic chain to form a three-dimensional, hydrogen-bonded network.
