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
ÁCl À , contains two crystallographically independent cations and two chloride ions. The crystal structure is stabilized by intramolecular O-HÁ Á ÁO, and intermolecular N-HÁ Á ÁCl and O-HÁ Á ÁCl hydrogen bonds.
