O, crystallizes in an infinite two-dimensional polymeric network due to intermolecular N—H⋯O hydrogen bonding. Intramolecular N—H⋯N and intermolecular C—H⋯N interactions are also present. The 3,4-dimethylphenyl unit is disordered over two sites with an occupancy ratio of 0.677 (5):0.323 (5). The dihedral angle between the benzene rings of the disordered components is 2.6 (6)°.
