1-[(Cyclohexylidene)amino]-3-(prop-2-en-1-yl)thiourea

Abstract

The asymmetric unit of the title compound, C10H17N3S, consists of three symmetry-independent molecules with distinctly different conformations, as indicated for example by the C—N—C—C torsion angles of −155.9 (3), 89.9 (3) and 81.1 (4)° along the bond between thiourea and allyl units. In the crystal, molecules are connected via N—H...N and N—H...S hydrogen bonds into chains extending along [110] that are further associated through C—H...N interactions into layers parallel to (001). The allyl group in one of the independent molecules is disordered over two sets of sites with an occupancy ratio of 0.853 (6):0.147 (6).
