A series of mononuclear penta‐coordinated halide Co III complexes with intermediate S =1 spin state has been investigated. Their magnetic anisotropy is sensitive to the nature of the halide in an unexpected way: the largest value was found for the chloride compound and the smallest for the iodide one. This study evidences that contemporary computational methods are powerful tools to predict and rationalize the magnetic anisotropy in such systems. However, for each metal ion, at each oxidation and spin state, benchmark studies are required to define magneto‐structural correlations. The authors gratefully thank Dr. Sylvain Bertaina for his assistance in the design of the cover illustration. More information can be found in the Full Paper by M. Orio, C.
