R. Gilardi, R. Evans and M.-X. Zhang

Abstract: The title compound, (2E)-3-[(1E)-2-(5-nitroisoxazol-3-yl)vinyloxy]prop-2-enal, C₈H₆N₂O₅, was an unexpected product of the direct reaction of furan and nitroacetylene. It crystallizes in the monoclinic space group P2₁/c, and is an unsaturated compound with a density of 1.507 g cm^-3. As a result of cooperative C-HO hydrogen bonding, the title compound forms centrosymmetric planar dimers, which pack in stacks of almost-planar parallel layers.
