1-Benzoyl-3,3-bis-(propan-2-yl)thio-urea.

Two independent thio-urea derivatives comprise the asymmetric unit of the title compound, C(14)H(20)N(2)OS. The major difference between the mol-ecules relates to a twist in the relative orientation of the benzene rings [torsion angles = 4.5†(2) and -19.9†(2)° for the two independent mol-ecules]. The thio-carbonyl and carbonyl groups lie to opposite sides of the mol-ecule as there are twists about the central N-S bond [torsion angles = 83.90†(15) and 81.77†(15)°]. Supra-molecular chains extending parallel to [101] with a stepped topology and mediated by N-H⋯O hydrogen bonding feature in the crystal structure. C-H⋯O and C-H⋯π inter-actions are also present.
