2,5-Dimethoxybenzonitrile
Abstract
In the title molecule, C9H9NO2, the non-H atoms are essentially coplanar with a maximum deviation of 0.027 (2) Å for the C atom of one of the methyl groups. In the crystal, the molecules are arranged into centrosymmetric pairs via pairs of C—H...O and C—H...N interactions whereas π–π stacking interactions between the benzene rings [centroid–centroid distance 3.91001 (15) Å] organize them into polymeric strands propagating along the a-axis direction. There is a step of 0.644 (2) Å between the two planar parts of the centrosymmetric pair. In neighboring strands related by the n-glide operation, the aromatic rings are tilted by 29.08 (2)°.
