Question
Using valence bond theory, predict the hybridization and magnetic character of the following:
[CoF6]3– [Atomic number of Co = 27]
Advertisements
Solution
[CoF6]3– orbitals of Co2+ ion:
Co2+ undergoing sp3d2 hybridisation:
[CoF6]3– outer orbital or high-spin complex:
Hybridization = sp3d2
Magnetic Nature = Paramagnetic
