Octahedral complex ${\left[Rh\left({\mathrm{NO}}_2\right)(\mathrm{SCN})(en{)}_2\right]}^{+}$can exist in a total number of 12 isomeric forms (including stereoisomers).

If complex ${\left[Ni(en{)}_3\right]}^{2+}$ has ' $x$ ' number of chelate ring and ' $y$ ' number of stereoisomer then $\mathrm{x}+\mathrm{y}$ will be 6 .

The number of geometric isomers possible for the complex $\left[M(AB)a_2{b}_2\right]$ is 4 . (Where $\mathrm{AB}\to$ Unsymmetric bidentate ligand. $a,b\to$ monodentate ligands)
