5,7-Dimethoxy-2-phenyl-4H-chromen-4-one
The asymmetric unit of the title compound, C(17)H(14)O(4), contains two independent molecules which differ in the relative orientations of the phenyl rings with repect to the essentially planar [maximum deviations of 0.029 (2) and 0.050 (2) Å in the two molecules] chromene fused-ring system, formi...

| Sumario: | The asymmetric unit of the title compound, C(17)H(14)O(4), contains two independent molecules which differ in the relative orientations of the phenyl rings with repect to the essentially planar [maximum deviations of 0.029 (2) and 0.050 (2) Å in the two molecules] chromene fused-ring system, forming dihedral angles of 10.3 (5) and 30.86 (5)° in the two molecules. The crystal structure is stabilized by weak C—H⋯O and C—-H⋯π interactions, and π–π stacking interactions. |
