    • While this manuscript was under revision, a paper appeared in Inorg. Chem. by Brewer et al. (ref 7) describing structurally three of the complexes, crystallized here with different counteranion. In this paper, only the structure of the entirely new [Fe(II)(L2H)] complex is detailed. To avoid any redundancy, other structural data have been moved to the Supporting Information. However, complex preparations are reported in the Experimental Section as different counteranions have been used.

    • Spin states for similar compounds have been published elsewhere (see refs 7, 10, 13, 14, 16, 17, 18). A systematic investigation of spin state equilibrium by Mössbauer spectroscopy can be found in Brewer's article (see ref 7). We have thus chosen to not focus on spin states here.

    • 3)), we noted a very insoluble black precipitate formation at intermediate pH when the experiment was done in anaerobic conditions. The IR spectrum is in agreement with a mixed compound formed by self-assemblage of protonated and deprotonated iron(II) complexes in 1/1 ratio. A similar type of layout has been recently published in the case of a 2-Me-imidazol-4-yl Fe(II) compound (see ref 14).
