2,2′-(Quinoxaline-2,3-diyl)diphenol dimethylformamide solvate

Abstract

In the title compound, C20H14N2O2·C3H7NO, the quinoxaline ring forms dihedral angles of 64.9 (2) and 30.9 (2)° with the two substituted benzene rings, which are themselves inclined at 58.4 (2)°. An intramolecular O—H...N hydrogen bond occurs. In the crystal, molecules are linked through intermolecular O—H...O hydrogen bonds.
