4-Bromo-3-hy-droxy-3-(4-hy-droxy-2-oxo-2H-chromen-3-yl)indolin-2-one.

ABSTRACT: In the mol-ecule of the title compound, C(17)H(10)BrNO(5), the indoline system and the attached coumarin ring are each essentially planar with maximum deviations of 0.074?(2) and 0.062 (2)?Å, respectively. The dihedral angle between them is 85.09?(3)°. In the crystal, all heteroatoms (except for the coumarin oxo O atoms) are involved in intra- and inter-molecular hydrogen bonds. An intra-molecular O-H?O hydrogen bond occurs. In the crystal, mol-ecules are linked through O-H?O, N-H?O and C-H?O contacts, forming a complex three-dimensional structure.

In both components, a pair of intra-molecular O-H?O inter-actions generate rings of S(8) graph-set motif. In the crystal, the mol-ecules are linked by inter-molecular C-H?O inter-actions, forming chains along the b axis. The structure is further stabilized by ?-? inter-actions with centroid-centroid distances of 3.594?(2) and 3.608?(5)?Å.
