title: (2-Chloro-3,5-dinitro-phen-yl)(piperidin-1-yl)methanone.
abstract: In the title compound, C(12)H(12)ClN(3)O(5), the piperidine ring adopts a chair conformation. One of the nitro groups is almost coplanar with the aromatic ring [O-N-C-C = -1.4 (2)°], whereas the other one is significantly twisted out of the ring plane [O-N-C-C = 34.7 (2)°]. The crystal packing is stabilized by inter-molecular π-π stacking inter-actions with centroid-centroid distances of 3.579 (3) Å.
