Independent Molecules

In the asymmetric unit of the title compound, C16H17N3O2S, there are two independent molecules (AandB), which show anEconformation with respect to the C=N bond. An intramolecular O—H...N hydrogen bond with anS(6) motif stabilizes the molecular structure. The terminal phenyl and benzene rings are almost orthogonal to each other, the dihedral angle being 87.47 (13)° for moleculeAand 89.86 (17)° for moleculeB. In the crystal, weak bifurcated N—H...(O,O) hydrogen bonds link the two independent molecules, forming a supramolecular chain with aC21(14)[R21(5)] motif along thebaxis. A weak C—H...O interaction is also observed in the chain.

The title compound, C10H5ClF2N2OS, was obtained by linking an amino heterocycle and a substituted benzoyl chloride. The dihedral angle between the two rings is 41.2 (2)° and the equalization of the amide C—N bond lengths reveals the existence of conjugation between the benzene ring and the thiazole unit. In the crystal, pairs of N—H...N hydrogen bonds link molecules into inversion dimers. Non-classical C—H...F and C—H...O hydrogen bonds stabilize the crystal structure.
