(9R,10R,10aR)-9-(2-Bromo-phen-yl)-10-nitro-6-phenyl-10,10a-dihydro-9H-benzo[c]chromene-8-carbaldehyde.
The title compound, C(26)H(18)BrNO(4), features a functionalized chromene. The cyclo-hexene ring adopts a sofa conformation and has the nitro group and the bromo-phenyl ring in an axial position. The ten atoms of the chromene moiety lie close to a common plane (r.m.s. deviation = 0.066 Å). The attached phenyl ring is twisted by 32.89 (10)° from the chromene plane. The crystal packing is stabilized by C-H⋯O inter-actions.
