Irisolidone (5,7-dihydroxy-6,4′-dimethoxyisoflavone) was isolated from the flowers of Pueraia lobata and its crystal structure was examined by X-ray single crystal diffraction. The crystal structure of irisolidone is monoclinic, space group P21/c with a = 15.491(9) Å, b = 7.895(4) Å, c = 13.321(7) Å, β = 110.546(9)° and Z = 4. Hydrogen bonding and aromatic ππ stacking assemble the title compound into a three-dimensional networking structure.
