2-(2-Hydroxy-3-methoxyphenyl)-6H-perimidin-6-one
The molecule of the title perimidine derivative, C(18)H(12)N(2)O(3), is essentially planar, the dihedral angle between the benzene and perimidine rings being 3.25 (5)°. The hydroxy and methoxy groups lie in the plane of the benzene ring to which they are bound [O—C—C—C = 179.96 (11)° and C—O—C—C...

Sumario: | The molecule of the title perimidine derivative, C(18)H(12)N(2)O(3), is essentially planar, the dihedral angle between the benzene and perimidine rings being 3.25 (5)°. The hydroxy and methoxy groups lie in the plane of the benzene ring to which they are bound [O—C—C—C = 179.96 (11)° and C—O—C—C = −177.96 (12)°]. An intramolecular O—H⋯N interaction generates an S(6) ring motif. In the crystal, molecules are linked by pairs of C—H⋯O interactions into dimers, which generate S(16) ring motifs. These dimers are arranged into sheets parallel to the ac plane and further stacked down the b axis by π–π interactions, with centroid–centroid distances in the range 3.5066 (8)–3.7241 (7) Å. |
