%X The title hydrated molecular salt, C12H9N2OS+¡¤Br ¡¤H2O, the aza-substituted six-membered ring is present as its keto tautomer instead of its aromatic tautomer. The dihedral angle between the fused ring system and the pyridinone ring in the cation is 6.91 (6)¡ã. In the crystal, bifurcated N¡ªH...(O,Br) and O¡ªH...Br hydrogen bonds and S...O contacts [S...O = 3.0526 (10)  ] connect the components into a three-dimensional network. The closest centroid¨Ccentroid distance between two ¦Ð-systems is 3.7420 (7)   between two benzene rings.
