Question
Using crystal field theory, draw energy level diagram, write the electronic configuration of the central metal atom/ion and determine the magnetic moment value in the following:
i. $\left[ CoF _6\right]^{3-},\left[ Co \left( H _2 O \right)_6\right]^{2+},\left[ Co ( CN )_6\right]^{3-}$
ii. $\left[ FeF _6\right]^{3-},\left[ Fe \left( H _2 O \right)_6\right]^{2+},\left[ Fe ( CN )_6\right]^{4-}$
i. $\left[ CoF _6\right]^{3-},\left[ Co \left( H _2 O \right)_6\right]^{2+},\left[ Co ( CN )_6\right]^{3-}$
ii. $\left[ FeF _6\right]^{3-},\left[ Fe \left( H _2 O \right)_6\right]^{2+},\left[ Fe ( CN )_6\right]^{4-}$
