N-[4-(4-Nitro­phen­oxy)phen­yl]penta­n­amide

The asymmetric unit of the title compound, C₁₇H₁₈N₂O₄, contains two independent mol­ecules (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 inter­actions (as N—H...O=C) results in distinct chains of A and B mol­ecules running parallel to the a-axis direction. C—H...O inter­actions also occur.
