Abstract

In the title compound, C(21)H(20)O(3), the tolyl ring makes a dihedral angle of 31.11 (6)° with the benzene ring of the chromanone unit. The pyrone ring adopts a half-chair conformation. The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O inter-action and the crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions and a C-H⋯π inter-action.
