“…The geometrical parameters of the chromone system in (I) are comparable to those of the related structures reported earlier (e.g. Hao et al, 2006). The chromone system is essentially planar.…”

Use of π–π forces to steer the assembly of chromone derivatives into hydrogen bonded supramolecular layers: crystal structures and Hirshfeld surface analyses

“…8 indicates that the molecular interactions in chromones are predominantly of the H/H and O/H types, which can account for 55% in SIMNEA 42 to 74.4% in 1. The contribution of O/H interactions varies from 14% in REBHEM 40 to 35% in GIRWAG 39 and can be attributed to various substitutions on the benzopyran moiety, which in turn facilitates the formation of different supramolecular synthons, leading to diverse crystal packing arrangements.…”
