A triclinic polymorph of (E)-2-(2-nitro-ethen-yl)furan.

ABSTRACT: The title compound, C(6)H(5)NO(3), crystallizes in the triclinic system with six independent mol-ecules 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 mol-ecules display an E configuration about the C=C double bond, with the dihedral angles between the planes of the furan rings and the nitro-alkenyl groups ranging from 0.61 (7) to 5.03 (7)°. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen-bonding inter-actions.
