RESUMO
The title compound, C11H10BrNO3, is close to planar with the benzo-furan unit and the ester group subtending a dihedral angle of 5.25â (2)°. The mol-ecular structure features an intra-molecular N-Hâ¯O inter-action. In the crystal, N-Hâ¯O hydrogen bonds involving carboxyl O-atom acceptors generate a chain extending along [201].
RESUMO
In the title compound, C14H14BrNO5, the ester group is disordered [occupancy ratio 0.52â (2):0.48â (2)]. The major component is nearly coplanar with the benzofuran plane, subtending a dihedral angle of 7.84â (2)°, while the amide group is twisted out of the benzofuran plane making a dihedral angle of 39.69â (2)°. An intra-molecular N-Hâ¯O hydrogen bond occurs. In the crystal, pairs of weak C-Hâ¯O hydrogen bonds link the mol-ecules into inversion dimers, which are further linked via strong N-Hâ¯O hydrogen bonds, generating a zigzag chain extending along [100].
