The title compound, (6,7‐dimethoxy‐3,4‐dihydro‐2H‐chromen‐4‐yl)(5‐methoxy‐2,2‐dimethyl‐2H‐chromen‐6‐yl)methanone, C24H25O6, is a modified rotenoid. In the crystal structure, the chromene ring is disordered, together with its attached methyl and methoxy groups. The molecules are packed as layers parallel to the ac plane. These layers are interconnected through C—H⋯O interactions to form a three‐dimensional network.
The title compound, C13H14O4, known as 8‐methyleugenitin, is a chromone isolated from the leaves of Mellaleuca cajuputi Powell. The chromone unit is essentially planar. The methyl and hydroxyl groups lie in the plane of the benzene ring while the methoxy substituent is perpendicular to it. An intramolecular O—H⋯O hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by intramolecular O—H⋯O and weak C—H⋯O hydrogen bonds, together with C—H⋯π and π–π interactions. Molecules are arranged in an antiparallel fashion into columns along the [100] direction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
