with two molecules in the asymmetric unit which differ slightly in conformation. Intermolecular N-H ... N and C-H ... O interactions generate a hydrogen-bonded ring system between the alternating molecules, graph set R-2(2)(16), with N ... N distances of 3.021 (3) and 3.041 (3) Angstrom, and C ... O distances of 3.219 (3) and 3.296 (3) Angstrom along the hydrogen-bonded chains.
