Title: soluble Berlin Blue
Post by: chehemi123 on November 27, 2012, 05:12:58 PM

hi guys..

i´m looking for an orbital energy diagram of soluble Berlin Blue:

K[FeIIIFeII(CN)6]

can you help me?

hey... i found an orbital energy diagram of CN^- and Fe[(H₂O)₆]²⁺.

I need the energy diagram of KFe(III)[Fe(II)(CN)₆] (soluble berlin blue).
I am not sure how i can combine the diagram of CN^- with the diagram of Fe²⁺ and Fe³⁺. Can I put them all in one diagram or do I have to make 2?

I hope you can understand my question..
(I am from Switzerland actually and studying in America)

TIA

Do you know why there are 12 σ electrons of 6 H₂O in the Fe[(H2O)6]²⁺ diagram?

I hope I am not annoying, but it would be great if you could just have a little look at my idea.

I don't know how to combine the two diagrams of the hexacyanoferrates [Fe(CN)₆]^4- and [Fe(CN)₆]³⁺...so that we have K[Fe(III)Fe(II)(CN₆)].

can anyone help me please?  :-\
