(E)-5-[1-Hydroxy-3-(3,4,5-trimethoxyphenyl)allylidene]-1,3-dimethylpyrimidine-2,4,6-trione: crystal structure and Hirshfeld surface analysis
In the title compound, C(18)H(20)N(2)O(7), the dihedral angle between the aromatic rings is 7.28 (7)° and the almost planar conformation of the molecule is supported by an intramolecular O—H⋯O hydrogen bond, which closes an S(6) ring. In the crystal, weak C—H⋯O hydrogen bonds and aromatic π–π stac...
