2-Oxo-2H-chromen-4-yl 4-methylbenzoate
The asymmetric unit of the title compound, C(17)H(12)O(4), 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 R...

Sumario: | The asymmetric unit of the title compound, C(17)H(12)O(4), 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 R (2) (2)(8) centrosymmetric dimers via C—H⋯O hydrogen bonds. These dimers are stacked by C—H⋯O hydrogen bonds, resulting in R (2) (2)(18) and R (3) (2)(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. |
