Abstract
The title compound, 2,2′:4,4′′:4′,4′′′-quaterpyridine (Qtpy), C20H14N4, crystallizes in the triclinic P\overline{1} space group and has half of the molecule in the asymmetric unit, corresponding to 4,4′-bipyridine (4,4′-bpy) that serves as the building block for the molecule. C4,4′-bpy—N—C4,4′-bpy and/or N—C4,4′-bpy—C4,4′-bpy bond-angle parameters show that the 4,4′-bpy ligands are highly rigid, displaying values lower than the linear bond angle of 180°. In the crystal, the 4,4′-bpy units are seen to be facing each other in relatively close proximity. The most important interactions on the Hirshfeld Surface of the compound are C—H...N/H...N—C interactions (constituting 10.6% and 7.6% of the total surface).
