The title compound, C(26)H(18)Cl(2)O, is a heterocyclic structure consisting of a benzo[f]chromene ring and two aromatic rings. The non-H atoms of the benzo[f]chromene ring are almost coplanar (rms deviation = 0.107 Å), and the methyl C atom lies 1.340 (4) Å from the mean plane of the benzo[f]chromene ring. The chromene ring forms dihedral angles of 88.45 (2)° with the benzene ring linked to the quaternary C atom and 50.74 (3)° with the benzene ring linked to the 3-position, while the dihedral a ...[more]
