Spin states when describing transition metal coordination complexes refers to the potential spin configurations of the central metal's d electrons. For several oxidation states, metals can adopt high-spin and low-spin configurations. The ambiguity only applies to first row metals, because second- and third-row metals are invariably low-spin. These configurations can be understood through the two major models used to describe coordination complexes; crystal field theory and li… WebDec 2, 2024 · For a high spin complex like [ F e B r X 6] X 3 −, the splitting is small and so it is more energetically favorable to "promote" electrons to the upper orbitals than to pair them. Getting back to your example, C u X + and C u X 2 + tend to form singlet and doublet spin state complexes, respectively.
