The crystal structures of two bromo–hydroxy–benzoic acid derivatives, namely, methyl 4-bromo-2-(methoxymethoxy)benzoate, (I), and 4-bromo-3-(methoxymethoxy)benzoic acid, (II), are compared. Compound (II) crystallizes with two independent molecules in the asymmetric unit. In the crystal structures of both compounds, two-dimensional architectures are formed principally by C—H⋯O hydrogen bonds, and by Br⋯O interactions in (I) and by π–π interactions in (II).

Both methyl 4-bromo-2-(methoxymethoxy)benzoate and 4-bromo-3-(methoxymethoxy)benzoic acid crystallize with two independent molecules in the asymmetric unit, forming two-dimensional architectures primarily through C-HO hydrogen bonds
