Ok, So I am working on a dye sensitizers, and I want to attach polypyridyl groups to an Fe atom. All the literature I have seen uses the the Fe +2
ion, but could the Fe +3 ion have polypyridyl groups? Also, I was wondering how polypyridyl Iron would be made in the lab? like what
procedures/chemicals would I use?

Is this the one you want? [Fe(bipy)3]2+
I believe it could be made by adding 2,2 -bipyridine to a either +2 or +3 Iron, (I would just try and see which one works)
I've actually wanted to make the Ruthenium complex, but I don't have the bipyridine, I have pyridine, but this needs to be catalyzed using "Raney
nickle" some kind of nickle-aluminum alloy.
Sorry,my knowledge isn't extensive about this.
(Off topic) Speaking of which if anyone knows a non-S.Aldrich company that sells Raney nickel... I'd love to hear!

Usually when we make complexes in the lab, we dissolve the ligand and metal salt in a solvent like THF. Iron usually sticks pretty well to ligands, at
the most gentle heating can encourage the metallation. If you want the iron (II) complex then use an iron (II) salt, otherwise you will have to deal
with reducing the iron (III) complex.

Ok, So just add the salt to a solution of the ligand sounds easy enough. Does the anion of the salt matter? For instance when creating [Fe(bipy)3]2+
could a a halide salt be used? or possibly an organic salt?
Also, if I wanted to add carboxyl groups to some of the rings how would be the best way to do that? And would it have to happen before or after the
ligand binds to the metal?
