✦ Synopsis


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 pK a values of different acids and their hydrogen bond distances in complexes with 2',6'-dimethoxyflavone.
