Magnetic susceptibility equation for dinuclear high-spin cobalt(II) complexes considering the exchange interaction between two axially distorted octahedral cobalt(II) ions

A new magnetic susceptibility equation has been obtained for dinuclear high-spin cobalt(II) complexes considering the exchange interaction between two axially distorted octahedral cobalt(II) ions. A computational program has been developed, and the temperature dependencies of the magnetic susceptibility have been demonstrated. A characteristic χA versus T curve due to the zero-field splitting was shown when the distortion parameter v was positive.
