6-Hydr­oxy-3-(hydroxy­imino)indolin-2-one

In the title compound, C(8)H(6)N(2)O(3), the indol-2-one system is almost planar [maximum deviation = 0.010 (3) Å]. In the crystal structure, inter­molecular N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. π–π contacts between the indole ring systems [cent...

Sumario:In the title compound, C(8)H(6)N(2)O(3), the indol-2-one system is almost planar [maximum deviation = 0.010 (3) Å]. In the crystal structure, inter­molecular N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. π–π contacts between the indole ring systems [centroid–centroid distances = 3.494 (1), 3.731 (1) and 3.736 (1) Å] may further stabilize the structure.
