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 hydro

The structures of two solid inclusion compounds with the 2',6'-dimethoxyflavone host molecule (1) were investigated by single-crystal x-ray analysis. Both compounds, 1 ร trichloroacetic acid (1:1) and 1 ร chloroacetic acid (1:1) crystallize in non-centrosymmetric groups Pna2 1 and P2 1 2 1 2 1 , res
