N,N'-Bis(phenyl-carbamo-thio-yl)benzene-1,3-dicarboxamide

The asymmetric unit of the title compound, C22H18N4O2S2, contains two mol-ecules. In one of them, the dihedral angles between the central benzene ring and the phenyl rings are 16.97 (8) and 20.97 (8)°, while the phenyl rings make a dihedral angle of 37.87 (8)°. In the other mol-ecule, the corresponding values are 34.92 (7), 53.90 (7) and 60.68 (8)°, respectively. In each mol-ecule, two intra-molecular N-H⋯O hydrogen bonds generate S(6) rings and a short C-H⋯S contact also occurs. In the crystal, N-H⋯S, N-H⋯O, C-H⋯O and C-H⋯S inter-actions link the mol-ecules into a three-dimensional network.
