Experimental data and software corresponding to the publication: "Magnetospectroscopic Studies of a Series of Fe(II) Scorpionate Complexes: Assessing the Relationship between Halide Identity and Zero-Field Splitting". Experimental data include: EA, FIRMS, HFEPR, magnetometry data (both susceptibility and VTVH measurements), 57Fe Mössbauer, NIR Absorption, NMR, PXRD, and X-Band EPR data. MATLAB scripts for the AOM modeling (written by Mihail Atanasov and edited by Daniel J. SantaLucia) as well as software used for LFT fitting (written by Joshua Telser) are also included.
