title: (4,6-Diamino-1,3-phenyl-ene)bis-(phenyl-methanone).
abstract: In the mol-ecule of the title compound, C(20)H(16)N(2)O(2), two intra-molecular N-H⋯O inter-actions occur. The mol-ecular chains are linked by N-H⋯π and C-H⋯π inter-actions into a three-dimensional network, which seems to be very effective in the stabilization of the crystal structure.
