3,3′-(Quinoxaline-2,3-diyldimethylene)bis(pentane-2,4-dione)

Abstract

In the title compound, C20H24N2O 4 the quinoxalinediyl bridging group separates two β-diketone groups, which are found to be in a pseudo-frara configuration. The major contributing packing forces are π-π interactions and weak but influential C-H⋯O hydrogen bonds. © 2005 Internationa Union of Crystallography Printed in Great Britain - all rights reserved.
