A substituted diaminoquinoxaline, 2,3-diethyl-N5,N8-di(quinolin-8-yl)quinoxaline-5,8-diamine, was synthesized and characterized by a single-crystal X-ray diffraction study. The crystal structure of the molecule has a planar geometry with intramolecular hydrogen bonding. The hydrogen bonding is also evaluated in a solution state by spectroscopic techniques
