Tetrapodal pentadentate ligands are chelators that form square pyramidal coordination caps when bound to a single metal ion.1 Complexes incorporating these ligands have been studied in a wide variety of applications, for example as hydrogen evolution catalysts,2 water oxidation catalysts,3 enzyme mimics,4,5 redox mediators in dye-sensitized solar cells,6 and metal cluster systems exhibiting slow magnetic relaxation.7 In addition to their unique versatility, tetrapodal ligands are advantageous due to their ability to restrict substrate access to a single open coordination site on the metal center and to form discrete, mononuclear complexes with well-defined coordination environments. Moreover, these ligands can afford enhanced stability through the chelate effect compared to their analogous monoor bidentate counterparts, which is a desirable trait particularly for systems incorporating labile first-row transition metals.8 Recently, complexes of the neutral pentadentate ligand 2,6bis[1,1-bis(2-pyridyl)ethyl]pyridine (PY5Me2) and its derivatives have been extensively investigated in the areas of water reduction catalysis2 and molecular magnetism
