WebPre-Lab Questions . 1. The charge on this hexanitrocobalt complex is −3.The charge of each nitro ligand (NO 2−) is −1. What is the oxidation state (i.e., charge) of cobalt in this complex?2. An easy way to assign the number of d-electrons (the “d count”) in a transition metal ion is to first look at the periodic table and take note of which group the element is in. WebComplexes such as this are called "low spin". For example, NO 2 − is a strong-field ligand and produces a large Δ. The octahedral ion [Fe(NO 2) 6] 3−, which has 5 d-electrons, would have the octahedral splitting diagram shown at right with all five electrons in the t 2g level. This low spin state therefore does not follow Hund's rule.
