3-Chloro-N-(diphenyl­carbamothio­yl)benzamide

In the title compound, C(20)H(15)ClN(2)OS, the bond lengths and angles in the thio­urea group are typical of thio­urea derivatives. The C—N bond lengths in the center of the mol­ecule are shorter than the normal C—N single bond due to the resonance effects in this part of the mol­ecule. The conformation of the title mol­ecule with respect to the thio­carbonyl and carbonyl groups is twisted, as reflected by the C—N—C—O and C—N—C—N torsion angles of −4.4 (6) and −53.3 (5)°, respectively. Pairs of the mol­ecules are linked into centrosymmetric dimers, stacked along the c axis via inter­molecular N—H⋯S inter­actions. There are also weak inter­molecular C—H⋯O and C—H⋯S contacts in the structure.
