Homoleptic Ni II and Fe II complexes of the “large‐surface” phenanthroline‐type ligand 1,12‐diazaperylene (dap), [Ni(dap) 3 ](BF 4 ) 2 ( 1 ) and [Fe(dap) 3 ](PF 6 ) 2 ( 2 ), respectively, were synthesized. In the crystal structure the complex cation [M(dap) 3 ] 2+ (M = Ni, Fe) exhibits C 3 symmetry and interacts with three other cations by π‐π stacking. It forms a new metalla‐supramolecular assembly with a honeycomb structure containing nanochannels running parallel to the crystallographic c axis. Aggregation by π‐π stacking between metal complexes of “large‐surface” ligands should give new perspectives for inorganic supramolecular chemistry. (© Wiley‐VCH Verlag GmbH & Co.
