N,N′-Bis[(E)-quinoxalin-2-ylmethylidene]ethane-1,2-diamine

Abstract

In the molecule of the title compound, C20H16N6, the central C—C bond lies on a crystallographic inversion centre. The quinoxalidine ring is nearly planar, with a maximum deviation of 0.021 (2) Å from the mean plane. The crystal structure is stabilized by intermolecular C—H...N interactions, leading to the formation of a layer-like structure, which extends along the a axis.
