Abstract
The title compound, C13H10N2O4, adopts the keto-amine tautomeric form and displays an intramolecular N-H...O [N...O = 2.579 (2) Angstrom] and three intermolecular O-H...O [O...O = 2.561 (2) Angstrom] and C-H...O [C...O = 3.274 (2) and 3.318 (2) Angstrom] hydrogen bonds. The keto-amine structure is favoured by through-molecule conjugation between the hydroxy O atom and imine N atom. The dihedral angle between the planes of the two aromatic rings is 10.79 (4)degrees.This publication has 2 references indexed in Scilit:
