2-Methyl-3-(4-nitro-phen-yl)acrylic acid.

ABSTRACT: The title compound, C(10)H(9)NO(4), forms R(2) (2)(8) dimers due to inter-molecular O-H?O hydrogen bonding in the crystal structure. Two dimers are further linked to each other through two inter-molecular C-H?O hydrogen bonds, forming an R(3) (3)(7) ring motif. The nitro groups form an intra-molecular C-H?O hydrogen bond mimicking a five-membered ring. As a result of these hydrogen bonds, polymeric sheets are formed. The aromatic ring makes a dihedral angle of 42.84?(8)° with the carboxyl-ate group and an angle of 8.01?(14)° with the nitro group. There is a ?-inter-action (N-O??) between the nitro group and the aromatic ring, with a distance of 3.7572?(14)?Å between the N atom and the centroid of the aromatic ring.
