${\left[\mathrm{P}\mathrm{d}\left(\mathrm{F}\right)\left(\mathrm{C}\mathrm{l}\right)\left(\mathrm{B}\mathrm{r}\right)\left(\mathrm{I}\right)\right]}^{2-}$ has $\mathrm{n}$ number of geometrical isomers. Then, the spin-only magnetic moment and crystal field stabilization energy $\left[\mathrm{C}\mathrm{F}\mathrm{S}\mathrm{E}\right]$ of ${\left[\mathrm{F}\mathrm{e}{\left(\mathrm{C}\mathrm{N}\right)}_6\right]}^{\mathrm{n}-6}$ , respectively, are:
