The title compound, C6H5NO3, crystallizes in the triclinic system with six independent molecules in the asymmetric unit. In a previous study, the structure of the title compound was determined in the monoclinic P21/n space group at 100 K [Valerga et al. (2009 ▶). Acta Cryst. E65, o1979]. All six independent molecules display an E configuration about the C=C double bond, with the dihedral angles between the planes of the furan rings and the nitroalkenyl groups ranging from 0.61 (7) to 5.03 (7)°. The crystal structure is stabilized by intermolecular C—H⋯O hydrogen-bonding interactions.
