This means that the 2 electrons involved in the liaison come from the lone pair.<br/>My assumption is that the carbon lone pair will be stronger than the one from the nitrogen as there is a formal - charge on the carbon. <br/>This is important because the crystal field will depend on the strength of the ligand, which will be related to the &#34;quality of the bond&#34;.<br/><br/>Because Fe2+ has one more electron, I would have assumed that it is more favourable to have a large cristal field splitting, high spin configuration. I suspect the entire thing is more complicated as Fe3+ is not just surrounded by 6N and therefore there will be even more cristal field splitting. <br/><br/>I don&#39;t have a clear explanation on the specificity of Prussian blue so a lot of it is hand-wavy assumptions from basic cristal field theory that may not even be (directly) applicable here 2025-09-30T20:34:40Z https://yabu.me/nevent1qqsvx22gymmjar667afz6c7cjf47s7g6rhqa94vja4fpyqqznu79qzszyq89666xmj5kfzay7h4pwptayg7zr0gker3rg5d55e9f8ne7tj5q7nr24tu In reply to <a href='/nevent1qqsdr7d9lu599wx0j9r9ka0eu2phmvufl6k0xvrlssmt6739te79qlsmgwz35'>nevent1q…wz35</a><br/>_________________________<br/><br/>I am not sure I understand the question as I assume you know much better than I do about those things. <br/><br/>Iron in both cases is surrounded by 6 ligands (not the 4 you mention earlier, but it&#39;s a detail). <br/><br/>You would have crystal field splitting with lifting of the degeneracy between the t2g and eg. with the different electronic (Fe2+:3d6 and Fe3+: 3d5) configuratiion and cristal fields, you will be &#34;filling&#34; your robitals differently in Fe2+ the 6 electrons occupy the low energy t3g (S=0), while in Fe3+, each orbital (3t2g+2eg) has one electron (S=5/2). Each of those crystal field may be in the visible range (but not necessarily)<br/><br/>I assume that when you are trying to excite an electron from Fe2+, t2g, it will go into its own eg and then quickly decays into an eg from the Fe3+ (which should have a smaller local energy) and then Fe3+ t2g and finally back to Fe2+ t2g.
