Building on the foundational equations by R. Hoffmann et al. and O. Kahn and B. Briat, we propose here an approach to decompose magnetic coupling in dinuclear complexes with multiple coupling paths into ferromagnetic and antiferromagnetic contributions. We use CASSCF and NEVPT2 calculations in conjunction with M -O -M angle and M -O -M -N dihedral scans, where the exchange integral and the difference between the intra-side and interside Coulomb interaction integrals stay effectively unchanged, so that the squared changes in orbital energy differences can be related with the magnitude of the overall magnetic coupling strength.
