Magnetic analysis of a tetranuclear octahedral high-spin cobalt(ii) complex based on a newly derived magnetic susceptibility equation

Abstract

Here we report a versatile magnetic susceptibility equation for tetranuclear octahedral high-spin cobalt(II) complexes and a magnetic analysis for a tetranuclear defect cubane cobalt(II) complex based on this equation. We concluded that the interaction is essentially ferromagnetic despite the decrease in the χT product on cooling from 300 K, and the decrease is due to the spin–orbit coupling.
