of all four carboxamido nitrogens to the FeIII center in [Fe(PyPOMe)2]− giving rise to an FeN6 chromophore. This one N-to-O switch in donor atom makes the two complexes 1 and 2 very different. While complex 2 is low spin (g = 2.18, 1.94) much like the other reported FeIII bis complexes with two ligated 2,6-pyridinedicarboxamido units, complex 1 is highspin (g = 4.3). The spin flip due to a switch in
