Abstract: The title compound, C13H10N4O2S, was prepared through a cyclization reaction of 1,10-phenanthroline-5,6-dione and thiourea. The dihedral angle between the pyridine rings is 8.22 (2)°. In the crystal, molecules are connected by N-H...O, O-H...N, N-H...S and O-H...S hydrogen bonds, forming a three-dimensional network.
