The whole mol-ecule of the title compound, C14H9NO6, is generated by twofold rotation symmetry; the twofold axis bis-ects the nitro group and the benzene ring. The nitro group is inclined to the benzene ring by 14.42 (9)°. The prop-2-yn-1-yl groups are inclined to the benzene ring by 13 (2)° and to each other by 24 (3)°; one directed above the plane of the benzene ring and the other below. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(18) ring motif. The dimers are linked by further C-H⋯O hydrogen bonds, forming sheets lying parallel to (100). |
