in ring torsions and quinoxaline deformation.
Structural studies on a larger ring system,
that of 2,3-bis(benzimidazol-2-yl)quinoxaline29
which has ring torsion angles of 22.17◦ and
41.04◦, only has a quinoxaline plane deformation

fore, it is interesting to bring into play the nature
of packing. The majority of the compounds in
the table adopt variants of herringbone packing
motifs—utilizing a mixture of π–π interactions

and intermolecular C H interactions; but crys-
tals of 2,3-bis(benzimidazol-2-yl)quinoxaline are
more heavily directed by π–π layer stacking.29
Molecules in the bulkier quinoxaline pack as
tilted head-to-tail dimers that utilize stacking
interactions between the quinoxaline moiety and
a neighboring molecule’s larger ring substituent.
Therefore, the deformation of the quinoxaline
moiety is not due to intramolecular steric effects
alone.

benzo[g]quinoxaline. (Other structures have shown bidentate
binding via both pyridyl rings.)
