Crystal structure of 2-methoxy-1-nitro-naphthalene

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 angstrom) 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) angstrom. Equivalent data for molecule B are 0.008 A, 65.9 (2) and 0.198 (2) A, respectively. In the crystal, molecules are linked by weak C-H center dot center dot center dot O interactions, forming [100] chains of alternating A and B molecules. Weak aromatic 7r rr stacking contacts, with a range of centroid centroid distances from 3.5863 (9) to 3.8048 (9) angstrom, are also observed.
