L. Dobrzanska and G. O. Lloyd

Abstract: In the title compound, C₂₀H₂₄N₂O₄, the quinoxalinediyl bridging group separates two -diketone groups, which are found to be in a pseudo-trans configuration. The major contributing packing forces are - interactions and weak but influential C-HO hydrogen bonds.
