Chains of edge-fused hydrogen-bondedR₃³(22) rings in 5,3′-dihydroxy-3,6,7,4′,5′-pentamethoxyflavone

Abstract

The asymmetric unit of (I), showing the atomic numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Dashed lines indicate hydrogen bonds. organic compounds
