3-[2-Hydroxy-3-(2,4,6-trimethylphenyl)propyl]-3-methyl-1-phenylthiourea

In the title compound, C20H26N2OS, four non-H atoms of the thiourea unit are approximately planar (r.m.s. deviation = 0.005 angstrom); the phenyl and benzene rings are twisted out of this plane by 28.55 (7) and 60.00 (7)degrees, respectively. An intramolecular N-H center dot center dot center dot O hydrogen bond occurs. The hydroxy group is hydrogen bonded to the double-bond S atom of an inversion-related molecule, generating a hydrogen-bonded dimer in the crystal structure.
