All interatomic distances of the title compound, C 17 H 17 N 3 O 2 , are normal. The phenyl ring of the benzylaminomethyl substituent is disordered over two positions. The heteroatom ring of the quinoxolinone system shows a half-chair conformation. The molecules are held together by intermolecular N
The heterocycle of the quinoxalinone system exhibits a half-chair conformation. The value of the total puckering amplitude Q T is 0.391 (5) A Ê . The benzylaminomethyl part of the side branch is close to planar. This weighted-least-squares plane makes a dihedral angle of 67.45 ( 14) with the quinoxa
The title complex, 2,5-di-4-pyridyl-1,3,4-oxadiazole-hydroquinone (1/1), C 12 H 8 N 4 OÁC 6 H 6 O 2 , crystallized from a solvent mixture of methanol and water. O-HÁ Á ÁN hydrogen bonds link the molecules to give a chain structure.
