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

A. Abou, A. Djandé, R. Kakou-Yao, A. Saba and A. J. Tenon

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. [pi]-[pi] 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.
