title: 5,7-Bis(benz-yloxy)-2-[4-(benz-yloxy)phen-yl]-4H-chromen-4-one.
abstract: In the title compound, C(36)H(28)O(5), the terminal benzene rings are twisted at dihedral angles of 6.75 (12), 70.86 (14) and 82.02 (12)° with the respect to the central plana r[maximum deviation = 0.070 (3) Å] chromen-4-one ring system. In the crystal structure, π-π stacking is observed between parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.7459 (16) Å].
