Why is the CFSE for d6 not equal to -24Dq+3p in crystal field theory?

[flashmanbs]

at crystal field stabilization in strong field case
d4 CFSE=-16Dq+p
d5 CFSE=-20Dq+2p
d6 CFSE=-24Dq+2p
d7 CFSE=-18Dq+p
d8 CFSE=-12Dq
it was shuld be +3P and +4 P
why it be +p,2p,2p,p ?

Why do you believe that it should be + 3 and + 4? What equation are you using?

my Q explain why the CFSE =-24Dq+2p at d6 not =-24Dq+3p?
like u see in fig. if we put the 6`th electron we have 3 paring set so we was should add 3p to the CFSE why we count them as 2P?

You are right for this case where its Octahedral , scroll the link to page 9

Is this an Octahedral complex? Also did they mention a specific metal ligand complex ; sometimes an LS becomes HS should the actual CFSE is found to be positive with the incorporation of the pairing energy?
