The title compound, 1,6,7,12,13,18-hexaazatrinaphthylene (HATN) tetrachloro
form solvate, C24H12N6. 4CH(3)Cl, belongs to a series of planar bridging li
gands with an extensive delocalized pi -electron system. The planar molecul
es pack in pairs with a pi-pi stacking of a symmetry-related quinoline moie
ty and are surrounded by solvent molecules of chloroform. The latter are in
volved in C-H . . .N contacts with the six pyrazine N atoms.
