Abstract
In the structure of the title compound, C20H18N4O2, the N—H and C=O bonds are trans to each other and the amide O atoms are syn to the ortho amino N atom in the benzoyl rings. The amide groups form dihedral angles of 8.4 (2) and 13.8 (2)° with their respective benzoyl rings, and dihedral angles of 51.85 (16) and 51.19 (17)° with the phenylenediamine ring. In the crystal, a centrosymmetric dimer is formed by intermolecular N—H...O hydrogen bonds, resulting in an R22(14) descriptor on a unitary level of graph-set analysis, and three intramolecular N—H...O bonds also occur.
