摘要：
In the crystal structure of the title compound, C20H16N4O2, the two pyridine rings subtend dihedral angles of 39.0 (1) and 43.4 (2)degrees with the mean quinoxaline plane and 67.6 (1)degrees with each other. The orientation of the pyridine rings is such that their N-donors face each other (cis-cis conformation) with a separation of 3.169 (2) Angstrom. There exist significant pi-pi interactions responsible for the formation of stacks along the crystallographic a axis of the crystal.
