title: N-[4-(4-Nitro-phen-oxy)phen-yl]penta-n-amide.
abstract: The asymmetric unit of the title compound, C(17)H(18)N(2)O(4), contains two independent mol-ecules (A and B) differing principally in the conformations of the alkyl chains, anti for molecule A and gauche for molecule B. The dihedral angles between the aromatic rings are 82.51 (6) and 82.25 (6)° in the two molecules. In the crystal, amide-amide inter-actions (as N-H⋯O=C) results in distinct chains of A and B mol-ecules running parallel to the a-axis direction. C-H⋯O inter-actions also occur.
