title: 2,2'-(Quinoxaline-2,3-di-yl)diphenol dimethyl-formamide solvate.
abstract: In the title compound, C(20)H(14)N(2)O(2)·C(3)H(7)NO, 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 intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds.
