✦ Synopsis


The title compound, C 13 H 14 O 4 , 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-HÁ Á ÁO hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by intramolecular O-HÁ Á ÁO and weak C-HÁ Á ÁO hydrogen bonds, together with C-HÁ Á Á andinteractions. Molecules are arranged in an antiparallel fashion into columns along the [100] direction.
