title: (2E)-2-[2-(Cyclo-hexyl-carbamothio-yl)hydrazinylidene]-propanoic acid.
abstract: In the title thio-urea derivative, C(10)H(17)N(3)O(2)S, the carboxyl group and the least-squares plane through the cyclo-hexyl ring are twisted out of the plane through the central CN(3)S residue; the respective dihedral angles are 7.18 (8) and 62.29 (4)°. The conformation about the azomethine bond [1.275 (2) Å] is E. The NH groups are anti, with one forming an intra-molecular N-H⋯N hydrogen bond. The main feature of the crystal structure is the formation of linear supra-molecular chains along [110] mediated by alternating pairs of O-H⋯O and pairs of N-H⋯S hydrogen bonds.
