3-(4-Hydroxy-3-methoxy-2-nitrophenyl)acrylic acid

Abstract

Key indicatorsSingle-crystal X-ray study T = 298 K Mean (C-C) = 0.006 Å Disorder in main residue R factor = 0.095 wR factor = 0.243 Data-to-parameter ratio = 12.2 For details of how these key indicators were automatically derived from the article, seeThe title compound, C 10 H 9 NO 6 , has an E configuration, with the carboxyl group and the benzene ring located on opposite sides of the C C bond. Intermolecular O-HÁ Á ÁO hydrogen bonding helps to stabilize the crystal structure.
