title: t-3-Ethyl-r-2,c-6-bis-(4-methoxy-phen-yl)-1-nitro-sopiperidin-4-one.
abstract: In the title mol-ecule, C(21)H(24)N(2)O(4), the piperidine ring adopts a distorted boat conformation with the ethyl substituent in the axial position. The dihedral angle between the two benzene rings is 70.25 (9)°. An intra-molecular C-H⋯O inter-action is observed. In the crystal, mol-ecules are linked into a chain along the c axis by C-H⋯O hydrogen bonds and the chains are linked via weak C-H⋯π inter-actions.
