Abstract: In the title compound, C10H8Cl2N2O2S·0.5H2O, the atoms in the oxadiazole ring are essentially coplanar (r.m.s. deviation 0.010 Å). The crystal structure is stabilized by intermolecular N-HO hydrogen bonds involving the water molecule, which is situated on an a twofold rotation axis, and two organic molecules, leading to a thione tautomer in the solid state. The C atom attached to the oxadiazole ring adopts a typical sp3 hybridization. The dihedral angle between the mean plane of the benzene ring of the dichlorophenyl group and the mean plane of the oxadiazole ring is 74.18 (4)°. The crystal structure is stabilized by intermolecular N-HO and O-HS hydrogen bonds.
