Abstract: In the title compound, C12H16N4O2, the piperazine ring is in a slightly distorted chair conformation. In the mol­ecule, the mean plane of the nitro group is twisted by 8.0 (3)° from that of the benzene ring. Also, the mean plane of the 2-nitro­benzyl ring is twisted slightly from that of the piperazine ring, with an N-N=C-C torsion angle of -176.24 (11)°. In the crystal, pairs of weak C-H...O inter­actions link the mol­ecules into dimers approximately along [010].
