6,8-Dibromo-3-nitro-2-phenyl-2H-chromene

L.-J. Yan and S.-Y. Zhang

Abstract: In the title compound, C15H9Br2NO3, the chromene unit is not quite planar (r.m.s. deviation from planarity = 0.0888 Å). The dihydropyran ring adopts an envelope conformation with the phenyl-substituted C atom fused to the dihydropyran ring as the flap. The dihedral angle between the plane defined by this C atom and the adjacent C and O atoms and the mean plane of the dihydropyran ring excluding the phenyl-substituted C atom is 25.1 (3)°. The dihedral angle between the mean plane of the chromene unit and the phenyl ring is 85.7 (1)°. The crystal structure features C-H...O hydrogen bonds and Br...O contacts [3.289 (3) Å] involving the nitro O atoms.
