title: Bis[4-(4-amino-phenyl-sulfanyl)phenyl] ketone.
abstract: The mol-ecule of the title compound, C(25)H(20)N(2)OS(2), has imposed twofold rotation symmetry. The dihedral angle formed by the two crystallographically independent phenyl rings is 79.23 (7)°. In the crystal packing, the mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming chains running parallel to [102].
