Nitrile-substituted 2,2′-bipyridines and 1,10-phenanthrolines are predisposed to associate in sheets because they have flattened conformations and can form multiple C−H···N interactions close to the average molecular plane. The structures of crystals and monolayers adsorbed on graphite were determined by X-ray diffraction and scanning tunneling microscopy. The observation of closely similar molecular arrangements shows that weak intermolecular interactions can be used to produce homologous three- and two-dimensional structures by design, despite the effects of the underlying surface.
