Hello all!

Ive been a long time lurker of these forums, but finally registered to seek help for a problem im stuck on!

Ive constructed the following http://i.imgur.com/v2ldA7u.jpg MO diagram for a complex im trying to synthesize.

Am I on the right track?

The splitting and degeneracy of d orbitals makes my head hurt, please if you can share any knowledge it woud be greatly appreciated!

Specifically, will the a1g Molecular orbital be ocuppied by a lone pair from an oxygen? Or is it covalent with 1 copper and 1 oxygen electron??
