In “Pentaaquacyanido Iron (III) trichloridotricyanido cobaltate (III)”
Complex cation is$\left[\mathrm{F}{\mathrm{e}}^{\mathrm{I}\mathrm{I}\mathrm{I}}\right(\mathrm{C}\mathrm{N}\left)\right({\mathrm{H}}_2\mathrm{O}{)}_5{]}^{2+}$and complex anion is$\left[\mathrm{C}{\mathrm{o}}^{\mathrm{I}\mathrm{I}\mathrm{I}}{\mathrm{C}\mathrm{l}}_3\right(\mathrm{C}\mathrm{N}{)}_3{]}^{3-}$
Therefore complex is$\left[\mathrm{F}\mathrm{e}\right(\mathrm{C}\mathrm{N}\left)\right({\mathrm{H}}_2\mathrm{O}{)}_5{]}_3\left[\mathrm{C}\mathrm{o}\mathrm{C}{\mathrm{l}}_3\right(\mathrm{C}\mathrm{N}{)}_3{]}_2$
