Structural isomers of hexaammineiron(III) hexacyanidocobaltate(III)

Christopher Lucy  Follow

I have found the answer:

In the following case: $$\ce{[Fe(NH_3)_3(CN)_3][Co(CN)_3(NH_3)_3]}$$ Both the constituent entities are neutral and hence will exist independently, and thus will not form isomers of the original compound.

Well if the two metallic centers were connected (Fe-CN-Co) then they wouldnt exist independently. Of course formula would be different, but Im talking about practical aspect here, maybe pointlessly as such isomer counting has little to do with realism and more with training in 3D thinking.More

Pfft, it still could be a compound not necessarily a mixture. CN ligands are bridging, so most of reasoning in all this makes little practical sense.More

@Mithoron I guess thats what my teacher had in mind. This was just after we had been explained all the types of isomerizations.More

@Mithoron Could you elaborate as to how $\ce{CN}$ ligands being a bridging states that the above will exist as a compound? Please keep in in mind Im only 16 and have just started learning Coordination Chemistry- all I have learnt is nomenclature and Isomerism; no CFT and so on.More
