Abstract

In the title compound, C(29)H(22)O(4), the chromene ring is almost planar with a small puckering [0.143 (2) Å]. The crystal structure is stabilized by C-H⋯O and C-H⋯π inter-actions. Edge-to-face (centroid-centroid distances of 3.894 and 3.673 Å) and face-to-face (centroid-centroid distance of 3.460 Å) π-π-ring electron inter-actions are also observed.
