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.7a,c The PY5Me2
ligand exclusively contains pyridine donors, and indeed the vast majority of tetrapodal ligands in the literature contain neutral aliphatic or aromatic nitrogen-donating groups
