3-Benzoyl-1,1-dibenzyl­thio­urea

Two independent thio­urea mol­ecules comprise the asymmetric unit of the title compound, C(22)H(20)N(2)OS. The central N–C(=S)N(H)C(=O) atoms in each mol­ecule are virtually superimposable and each is twisted [C—N—C—S torsion angles = 121.3 (3) and −62.3 (4)°]. The mol­ecules differ only in terms of the relative orientations of the benzyl benzene rings [major difference between the C—N—C—C torsion angles of −146.6 (3) and −132.9 (3)°]. The presence of N—H⋯S hydrogen bonding leads to the formation of supra­molecular chains along the a axis. These are consolidated in the crystal packing by C—H⋯O inter­actions. The crystal was found to be a combined non-merohedral and racemic twin (twin law [Image: see text]00/0[Image: see text]0/001), with the fractional contribution of the minor components being approximately 9 and 28%.
