# Can we do column chromatography for the purification of metal complexs?

In case of organic ligands there are several techniques for purification, but in case of metal complex (using $\ce{Cr,Mn,Fe,Co}$ as central metals), I have not seen any literature for the purification of them except recrystallization.

Can we do column chromatography for the purification of metal complexes?

• Depends on the specific complex. Some are ameanable to columning, others decompose. I think generally if things are crystalline and will recrystallise its a whole lot easier to purify that way. Ferrocene and acetyl ferrocene are two classic examples of iron complexes that can be columned – NotEvans. Jul 27 '16 at 14:20
