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

摘要

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.
