摘要：

The crystal structures for 3-hydroxychromone and 5-hydroxychromone have been obtained. Both molecules exhibit intramolecular hydrogen bonding between the hydroxy group and the ketone oxygen atom. However, only the 3-hydroxy derivative contains hydrogen bonds between molecules. By comparing the current results with those obtained for the corresponding flavone derivatives, the effect of the B phenyl group on hydrogen bonding is inferred. (C) 2008 Elsevier Ltd.
