(I) ${\mathrm{K}}_3\left[\mathrm{Co}{\left({\mathrm{C}}_2{\mathrm{O}}_4\right)}_3\right]\to$ Only Optical isomerism → Octahedral geometry, Homoleptic complex (II) $\left[\mathrm{Pt}(\mathrm{CO}{)}_2{\left({\mathrm{PPh}}_3\right)}_2\right]\to$ Only Geometrical isomerism → Square planar, Heteroleptic complex (III) $\left[\mathrm{Co}{\left({\mathrm{H}}_2\mathrm{O}\right)}_3{\mathrm{F}}_3\right]\to$ Only Geometrical isomerism → Octahedral geometry, Heteroleptic complex

(IV) $\left[\mathrm{Co}(\mathrm{CN}{)}_2{\left({\mathrm{NH}}_3\right)}_4\right]\mathrm{Cl}\to$ Geometrical isomerism and Ionisation isomerism → Octahedral geometry, Heteroleptic complex
