2-Oxo-2H-chromen-4-yl 4-methoxybenzoate
In the title molecule, C(17)H(12)O(5), the chromen-2-one ring and the 4-methoxybenzoate side chain are inclined to one another at a dihedral angle of 69.82 (9)°. The crystal structure features parallel sheets of centrosymmetric R (2) (2)(6) dimers joined by a C(7) chain, resulting in centrosymetr...

Sumario: | In the title molecule, C(17)H(12)O(5), the chromen-2-one ring and the 4-methoxybenzoate side chain are inclined to one another at a dihedral angle of 69.82 (9)°. The crystal structure features parallel sheets of centrosymmetric R (2) (2)(6) dimers joined by a C(7) chain, resulting in centrosymetric tetramers of hydrogen-bonded molecules with graph-set motif R (4) (4)(40). These centrosymetric tetramers are connected by a pair of hydrogen bonds described by an R (2) (2)(8) ring motif and a C(7) chain via C—H⋯O interactions. In the structure, there are also π–π stacking interactions between chromene benzene and the six-membered heterocyclic rings [centroid–centroid distance = 3.691 (2) Å] and weak C=O⋯π interactions [O⋯(ring centroid) distance = 3.357 (3) Å]. |
