Aufbau Diagram of sp3d

[Jeffrey Doeve 2I]

I was thinking about how the relative energy difference between sp and p leads to e- not pairing. I was wondering how that would look like in sp3d and the leftover d orbitals. Is the energy difference between sp3d and d small enough for e- not to pair again? I am assuming it would probably be small enough, but was wondering if it could possibly be an exception.

Yes I believe sp3d hybridized orbitals are a thing and since Lavelle has not brought up exceptions yet, I don't think there are any.

sp3d hybridization and sp3d2 hybridization is what we see in more complex molecules than tetrahedral ones. The first leads to trigonal bipyramidal and other derivatives of that, whereas the second one leads to octahedral and derivatives of octahedral.
