    In Co(NH3)6Cl3, since the complex has a total charge of zero, ammonia has an oxidation number of 0, chlorine has an oxidation number of -1, cobalt has an oxidation number of +3. Therefore, there are four electrons in the d orbital of a cobalt in this complex. Figure 8 gives the possible high spin and low spin combinations for four d orbital electrons. The high spin config- uration has four unpaired electrons and the low spin configuration has two unpaired electrons. Figure 7. High and low…
