Abstract
In the title thiourea derivative, C10H17N3O2S, the carboxyl group and the least-squares plane through the cyclohexyl ring are twisted out of the plane through the central CN3S residue; the respective dihedral angles are 7.18 (8) and 62.29 (4)degrees. The conformation about the azomethine bond [1.275 (2) angstrom] is E. The NH groups are anti, with one forming an intramolecular N-H center dot center dot center dot N hydrogen bond. The main feature of the crystal structure is the formation of linear supramolecular chains along [110] mediated by alternating pairs of O-H center dot center dot center dot O and pairs of N-H center dot center dot center dot S hydrogen bonds.
