Crystal field theory considers purely ionic bond between metal and ligand. The five d-orbitals in an isolated gaseous metal are degenerate. The degeneracy of the d-orbitals is lost in prsence of ligand which is known as splitting of d-orbitals. Calculate crystal field stabilization energy in [Co(C_(2)O_(4))_(3)]^(3-) in terms of Delta_(0)

Answer»

`-2.4 Delta_(0)`
`+2.4 Delta_(0)`
`-3.6 Delta_(0)`
`-1.8 Delta_(0)`

SOLUTION :`d^(6) to t_(2g)^(2,2,2)eg^(0,0)`
CFSE`=-0.4xx6Delta_(0)=-2.4Delta_(0)`
