Résumé

In the title mol-ecule, C17H12O5, the chromen-2-one ring and the 4-meth-oxy-benzoate side chain are inclined to one another at a dihedral angle of 69.82 (9)°. The crystal structure features parallel sheets of centrosymmetric R2(2)(6) dimers joined by a C(7) chain, resulting in centrosymetric tetra-mers of hydrogen-bonded mol-ecules with graph-set motif R4(4)(40). These centrosymetric tetra-mers are connected by a pair of hydrogen bonds described by an R2(2)(8) ring motif and a C(7) chain via C-H⋯O inter-actions. In the structure, there are also pi-pi stacking inter-actions between chromene benzene and the six-membered heterocyclic rings [centroid-centroid distance = 3.691 (2) A] and weak C=O⋯pi inter-actions [O⋯(ring centroid) distance = 3.357 (3) A].
