Crystal structure of 2-methoxy-1-nitronaphthalene

Abstract

The asymmetric unit of the title compound, C11H9NO3, contains two mol­ecules, A and B. In mol­ecule 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 meth­oxy group deviates from the naphthyl plane by 0.022 (2) Å. Equivalent data for mol­ecule B are 0.008 Å, 65.9 (2)° and −0.198 (2) Å, respectively. In the crystal, mol­ecules are linked by weak C—H⋯O inter­actions, forming [100] chains of alternating A and B mol­ecules. 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.

“…As part of the authors' investigation of non-covalent bonding interactions in the organic solid states, title compound and homologue are compared to other related 1substituted naphthalene compounds, 1-acetyl-2ethoxynaphthalene, 30 2-methoxy-1-nitronaphthalene, 31 (3ethyl-6,7-dimethoxynaphthalene-1-yl)(phenyl)methanone, 32 1-actyl-2,7-dimethoxynaphthalene, 33 and 1-benzoyl-2,7dimethoxynaphthalene 20 (Figure 10). The first three compounds have asymmetric unit of P-1 space group and remaining two compounds exhibit P21/c and P21/n space groups, respectively.…”
