Explain the hybridization, geometry and magnetic property of [ CoF6]-3 on the basis of valence bond theory [ z of Co = 27].

In, [ CoF₆]^-3 the atom at the center has sp³d² hybridization.

Due to the presence of four unpaired electrons, it forms an octahedral complex exhibiting paramagnetic properties.

It uses outer 4d orbitals in sp³d² hybridisation to generate outer orbital, high spin, or spin free complexes.

Hence, the sp³d² hybridization, octahedral complex and paramagnetic property of CoF₆]^-3 on the basis of valence bond theory are shown above.
