Transition metal complex isomers
« on: December 02, 2018, 03:56:34 AM »

I've never come across such a complex, and I only know fac and mer isomers for complexes of the type MA3B3.

Still, even with MA2B4, I think there is a scenario where mer can be formed (trans case).

I'd say 2 of the geometric isomers I've drawn is of the fac-mer type. Is this correct?

Like you, I associate fac-mer isomerism with MA3B3 complexes, and cis-trans with MA4B2. Personally I would say none of your isomers are fac-mer.

Have you got all the linkage isomers? I don't know if they can be made practically, but theoretically you could have one -NO2 and one -ONO.

Yes, I agree with you on both points. I don't think there should be any fac-mer isomers.

I also thought it would be practically impossible to have one -NO2 and -ONO, but in theory it's definitely possible.
