Hi Everyone,

I have been looking into the world of octahedral organometallic complexes 

Molybdenum hexacarbonyl is a white colour and is a d6 compound. The carbonyl ligands are classsed as strong field so would induce a large octahedral splitting of the d orbitals resulting in low spin  

In low spin the six electrons would completely fill up the 3 t2g orbitals and there would be no unpaired electrons  

I am right in thinking that because there are no unpaired electrons to make a transition up into the eg orbitals after a photon of light is added, no colour frequency of light is absorbed and therefore all colours are reflected back as white or colourless? 

Kind Regards 

Nick.
