2-Nitrophenoxyacetanilide: a chain of rings generated by C—H⃛O hydrogen bonds
Abstract:In molecules of the title compound, C14H12N2O4, 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 Å, C…O = 3.2990 (17) Å and C—H…O = 156°] into centrosymmetric (14) dimers; these dimers are linked weakly into chains of alternating (14) and (40) rings by a second C—H…O hydrogen bond [H…O = 2.55 Å, C…O = 3.5006 (15) Å and C—H…O = 162°].
