The crystal structure of the 2′,6′‐dimethoxyflavone–2,6‐dimethoxybenzoic acid complex was determined. Owing steric hindrance of the methoxy groups, the two H‐bonded molecules are twisted. Earlier results were used to establish a relationship between the p K a values of different acids and their hydrogen bond distances in complexes with 2′,6′‐dimethoxyflavone. © 1998 John Wiley & Sons, Ltd.
