Abstract

The crystal structures of two substituted HATN (hexa­aza­tri­naphthyl­ene) derivatives, namely 2,3,8,9,14,15-hexa­methyl- and 2,3,8,9,14,15-hexa­phenyl-5,6,11,12,17,18- hexa­zatri­naphthyl­ene (HATNMe6 and HATNPh6), are reported. Whereas the structure of the methyl-substituted derivative (HATNMe6) contains no solvent mol­ecules (C30H24N6), the hexa­phenyl-substituted structure (HATNPh6) contains two mol­ecules of di­chloro­methane (C60H36N6·2CH2Cl2). This class of planar bridging ligands is known for its electron-deficient systems and its ability to form π–π stacking inter­actions. Indeed, in both crystal structures strong π–π stacking inter­actions are observed, but with different packing features. The di­chloro­methane mol­ecules in the crystal structure of HATNPh6 are situated in the voids and are involved in C—H...N contacts to the nitro­gen atoms of the pyrazine units.
