title: 1,1'-Diphenyl-3,3'-(p-phenyl-enedicarbon-yl)dithio-urea.
abstract: The mol-ecule of the title compound, C(22)H(18)N(4)O(2)S(2), lies across a crystallographic inversion centre. The central benzene ring forms dihedral angles of 29.39 (9) and 79.11 (12)°, respectively, with the thio-urea unit and the terminal phenyl ring. Intra-molecular N-H⋯O hydrogen bonds generate two S(6) ring motifs. In the crystal, mol-ecules are linked into chains along [10] by inter-molecular N-H⋯S hydrogen bonds.
