Why is[FeF6]3- ion paramagnetic while [Fe(CN)6]4-ion diamagnetic?
<p>In case of <strong>[FeF6]3–complex ion, </strong>the oxidation state of <strong>central iron metal is +3</strong>.</p>
<p>The atomic number of iron <a href="https://chemisfast.blogspot.com/2020/04/octet-rule-definition-limitations-of.html" rel="noopener ugc nofollow" target="_blank">metal : 26 </a>and that of ion(III)ion : 23. Valence shell electronic configuration of<strong> Fe(III) ion : [ Ar ] d5</strong>.</p>
<p>Co-ordination number of <a href="https://chemisfast.blogspot.com/2020/04/octet-rule-definition-limitations-of.html" rel="noopener ugc nofollow" target="_blank">central metal Fe(III)ion</a> : 6. Arrangement of<strong> [FeF6]3–</strong> complex ion :<strong> Octahedral.</strong></p>
<p>Now ligand<strong> F–</strong>, which is a weak field ligand. Under the influence of the octahedral</p>
