The crystal structure of capillarisin, which is one of the constituents of Artemisia capillaries, has been determined. The chromone ring system is nearly planar stabilized by an intramolecular hydrogen bond; the dihedral angle between the chromone and p-hydroxybenzyl moieties is 61.57(4)°. There are intermolecular π-π stacking interactions between the ring moieties correlated with symmetrical operations. The crystal structure is also stabilized by intermolecular hydrogen bonds.
