2-nitrophenoxyacetanilide: a chain of rings generated by C-H...O hydrogen bonds.
In molecules of the title compound, C(14)H(12)N(2)O(4), the conformation is dominated by an intramolecular N-H.O hydrogen bond in which one of the nitro O atoms is the acceptor. The molecules are linked by paired C-H.O hydrogen bonds [H.O = 2.41 A, C.O = 3.2990 (17) A and C-H.O = 156 degrees ] into centrosymmetric R(2)(2)(14) dimers; these dimers are linked weakly into chains of alternating R(2)(2)(14) and R(4)(4)(40) rings by a second C-H.O hydrogen bond [H.O = 2.55 A, C.O = 3.5006 (15) A and C-H.O = 162 degrees ].
