摘要：

In the title compound, C10H8Cl2N2O2S center dot 0.5H(2)O, the atoms in the oxadiazole ring are essentially coplanar (r.m.s. deviation 0.010 angstrom). The crystal structure is stabilized by intermolecular N-H center dot center dot center dot O 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 sp(3) 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)degrees. The crystal structure is stabilized by intermolecular N-H center dot center dot center dot O and O-H center dot center dot center dot S hydrogen bonds.
