Abstract
In the title compound, C11H10BrNO3, two independent molecules (A and B) crystallize in the asymmetric unit. The dihedral angles between the mean planes of the 4-bromophenyl ring and amide group are 24.8 (7) in molecule A and 77.1 (6)° in molecule B. The mean plane of the methylidene group is further inclined by 75.6 (4) in molecule A and 72.5 (6)° in molecule B from that of the amide group. In the crystal, N—H⋯O hydrogen bonds formed by amide groups and O—H⋯O hydrogen bonds formed by carboxylic acid groups are observed and supported additionally by weak C—H⋯O interactions between the methylidene and amide groups. Together, these link the molecules into chains of dimers along [110] and form R 2 2(8) graph-set motifs.
