Abstract
The structures of two solid inclusion compounds with the 2',6'-dimethoxyfla vone host molecule, 1, were investigated by single-crystal X-ray analysis. Both compounds, 1.3 -bromo-2,6-dimethoxybenzoic acid (1:1) and 1.3-chloro-2 ,6-dimethoxybenzoic acid (1:1) crystallize in the centrosymmetric group P ( 1) over bar. The complexation involves an intermolecular hydrogen bond betw een the carbonyl group of the flavone and the acidic hydrogen of the acid.
