As discussed

Outer Sphere Complex -

Complexes in which outer (nd) orbitals are used in hybridisation (sp3 d2

- wherein

For example: \left [ Co\;Cl_{6} \right ]^{4-}


 The given complex \left [ Cr\left ( NH_{3} \right )_{6} \right ]Cl_{3}, the complex is octahedral with hybridisation d2sp3. It is an inner orbital complex which paramagnetic in nature.

Cr^{3+}\Rightarrow 3d^{3}
