| Popis: | The title compound consists of a 2-hydroxy-4-methylphenyl ring, a 2,4,6-trimethoxyphenyl ring and a prop-2-en-1-one connecting bridge. The overall conformations of the title compound are discussed and compared with those of related structures. In the crystal, molecules are consolidated by O—H⋯O hydrogen bonds and weak C—H⋯O interactions. The title chalcone derivative, C19H20O5, adopts a trans configuration with respect to the olefinic C=C double bond. The 2-hydroxy-4-methylphenyl ring is coplanar with the attached enone bridge [torsion angle = −179.96 (14)°], where this plane is nearly perpendicular to the 2,4,6-trimethoxyphenyl ring [dihedral angle = 75.81 (8)°]. In the crystal, molecules are linked into chains propagating along [010] by an O—H⋯O hydrogen bond. These chains are further connected into centrosymmetric dimer chains via weak C—H⋯O interactions. The conformations of related chalcone derivatives are surveyed and all of these structures adopt a skeleton with two almost orthogonal aromatic rings. |
