The ground state electronic WebThe choice between high-spin and low-spin configurations for octahedral d 4, d 5, d 6, or d 7 complexes is easy. All we have to do is compare the energy it takes to pair electrons with the energy it takes to excite an electron to the higher energy (e g) orbitals. If it takes less energy to pair the electrons, the complex is low-spin. long tonic bandThe Δ splitting of the d orbitals plays an important role in the electron spin state of a coordination complex. Three factors affect Δ: the period (row in periodic table) of the metal ion, the charge of the metal ion, and the field strength of the complex's ligands as described by the spectrochemical series. Only octahedral complexes of first row transition metals adopt high-spin states. longton jcp address
