2-Oxo-2H-chromen-4-yl 4-methylbenzoate

Abstract

The asymmetric unit of the title compound, C17H12O4, consists of two independent molecules. The chromen-2-one ring and the 4-methylbenzoate side chain are inclined to one another at a dihedral angle of 64.79 (10)° in one molecule and 88.3 (1)° in the other. In the crystal, molecules form R22(8) centrosymmetric dimers via C—H...O hydrogen bonds. These dimers are stacked by C—H...O hydrogen bonds, resulting in R22(18) and R32(16) ring motifs. π–π stacking interactions between two parallel chromen-2-one rings, with centroid–centroid distances of 3.743 (1) and 3.771 (1) Å, are also present.
