| Popis: | In the title coumarin derivative, C20H18O4, the benzene ring of the benzoate group is oriented at a dihedral angle of 57.55 (9)° with respect to the planar chromene ring system [maximum deviation from plane is 0.027 (2) Å]. In the crystal, inversion-related molecules are linked into dimers via C—H...O hydrogen bonds, generating R 2 2(12) loops. The dimers are linked by further C—H...O hydrogen bonds forming layers, parallel to the bc plane, which are linked via C—H...π interactions, forming a three-dimensional framework |
