摘要：

The title compound, C(6)H(5)NO(3), 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 P2(1)/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)degrees. The crystal structure is stabilized by intermolecular C-H...O hydrogen-bonding interactions.
