Abstract:
The asymmetric unit of the title compound, C11H9NO3, contains two mol-ecules, A and B. In mol-ecule A, the dihedral angle between the planes of the naphthalene ring system (r.m.s. deviation = 0.003 Å) and the nitro group is 89.9 (2)°, and the C atom of the meth-oxy group deviates from the naphthyl plane by 0.022 (2) Å. Equivalent data for mol-ecule B are 0.008 Å, 65.9 (2)° and -0.198 (2) Å, respectively. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, forming [100] chains of alternating A and B mol-ecules. Weak aromatic π-π stacking contacts, with a range of centroid-centroid distances from 3.5863 (9) to 3.8048 (9) Å, are also observed.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
