Abstract
The crystal structure of the 2',6'-dimethoxyflavone-2,6-dimethoxybenzo ic acid complex was determined. Owing steric hindrance of the methoxy groups, the two II-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'-dimet hoxyflavone.
