The Kβ1,3-M1 values for 1 and 2 are ~0.3 eV lower than that for Co(II) acetate, resulting from decreased 3p-3d exchange coupling and lower splitting of the Kβ1,3 and Kβ' features. This behavior is consistent with greater Co-ligand covalency in 1 and 2 (Co-P, Co-N, Co-Cl) compared to Co(II) acetate (Co-O), arising from the lower ligand electronegativity and thus greater covalent character of the metal-ligand bonds in 1 and 2. The Kβ1,3-M1 values for 3 and 4 are ~0.7 eV lower than that for cobaltocene (s=1/2), indicative of low 3p-3d exchange coupling, likely resulting from differences in Co-ligand covalency and the closed-shell nature of the dicobalt compounds. When comparing to a closed-shell reference, Co(acac)3, we find that the first moment values are ~0.6 eV lower for 3 and 4, demonstrating a highly covalent nature of the bonding in these compounds. Uncertainty remains about whether this covalency results from a direct Co-Co interaction or multicentered bonding mediated by the bridging ligands, thus requiring further spectroscopic and computational analysis described in section 2.2 and 2.3.
