The synthesis and characterisation of bis(terpyridine)‐derived ligands which are capable of forming [2×2] grid‐like complexes is presented. Additional pyridine substituents on these ligands do not interfere with the complexation process. Adsorbing one of the pure ligands on highly ordered pyrolytic graphite (HOPG) shows a highly ordered structure stabilised by additional weak intermolecular C−H⋅⋅⋅N hydrogen bonds partially through the extra‐pyridines as could be shown by scanning tunneling microscopy (STM) investigations. Similar adsorption experiments with one of the corresponding [2×2] Co II grid‐type complexes on graphite, led also to a well‐organised structure with interdigitation of the extra‐pyridine moieties.
