The magnetic moment of coordination compounds is measured through magnetic susceptibility experiments. This involves applying an external magnetic field and observing the extent of magnetization. The results provide information about the number of unpaired electrons in the complex. Diamagnetic compounds with all electron spins paired exhibit no magnetic moment, while paramagnetic compounds with unpaired electrons show a magnetic moment. The magnetic data, along with theoretical models like Crystal Field Theory and Ligand Field Theory, aid in understanding the electronic structure, bonding, and geometry of coordination compounds, contributing to insights into their properties and behaviors.
