a) The terms low spin and high spin apply only to complexes of d-metal ions having certain numbers of d electrons. This implies that certain d-metal ions can have only one electron configuration and a distinction between low- and high-spin complexes is not possible. For what number of d electrons are both high- and low-spin octahedral complexes possible?
