| Popis: | 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 R22(8) graph-set motifs. |
