    • The reaction of FeCl2 with H(Mabiq) in mixtures of MeCN/CH2Cl2or MeCN only leads to dark green solutions after several hours stirring. However, a mixture of products always results even when CH2Cl2 is avoided. A single crystal of Fe II(Mabiq)(MeCN)Cl was isolated as a product of recrystallization of the green solid product from CH2Cl2/ diethyl ether. Structural details can be found in the Supporting Information, Figure S2 and Table S1. Upon addition of CH2Cl2 to crude solids of FeII(Mabiq)(MeCN)Cl or 4a, the solutions become red, with spectral features similar to 3

    • eff vs T plot from 0-6 K (Supporting Information, Figure S12) can be attributed to solid-state intermolecular interactions and requires the theta Weiss value to properly fit the data. The crystal packing structure of compound 5 reveals pairs of Fe molecules separated by a distance of 3.325 Å as evidence for dimeric interactions.
