Reference for diamagnetic vs paramagnetic

[JustinLevy]

I am not a chemist, so I have a feeling I'm going about searching for the wrong key words or something.

What I want is a table of Fe+2 and Fe+3 compounds in solution (ie. different ligands like CO, CN-, etc.), listing each compound as paramagnetic or diamagnetic. I've searched for a nice chemistry review article that may have this, but this seems too "old" of information so I can't find anything good.

Maybe a good textbook? Or maybe I just don't know how to search for articles well without getting all kinds of noise to sift through.

Please, can anyone help?
Anyone take inorganic chem and can check their textbook, or recommend one?

Try the CRC handbook

Fe³⁺ has an odd number of electrons, so at least one electron will be unpaired.

I looked through the online one which allowed searching. Found some iron compounds under a table for "MAGNETIC SUSCEPTIBILITY". I didn't think of looking for that. Maybe with that keyword I can find some more info online, but I'm still struggling to find a huge list. The CRC one was mostly limited to halogen salts. So they didn't even have CO or CN- ligands listed, let alone some common bidentite ones.

Fe³⁺ has an odd number of electrons, so at least one electron will be unpaired.

Some ionic complexes have two metallic centers, and so I have been warned that there are cases which are surprisingly diamagnetic. Also, apparently most Fe+2 compounds still have unpaired electrons, unless the ligands are 'just right' or something ... I wish I understood this better. Google books spits out snippets from some chemistry textbooks, so maybe I'll hit up the chemistry library later. But there has got to be some good information on the internet somewhere, if only I knew how to search for it better.

d electron spin states

Keep in mind Fe²⁺ is d6, while F³⁺ is d5.

also, a tetrahedral ligand field will result in two lower energy orbitals and three higher energy, as opposed to three lower and two higher for octahedral complexes.
