Likewise, low-spin d6 would not be distorted. I am not sure, however, why high spin d6 would not show distortions. Edit: See page 4 of this link 40 proof whiskey WebJun 23, 2024 · The loss of exchange energy increases the stability. As the stability increases, the ionization becomes more difficult. There is no loss of exchange energy at ( d X 6) configuration. M n X + has ( 3 d X 5) ( 4 s X 1) configuration and configuration of C r X + is ( d X 5), therefore, ionization enthalpy of M n X + is lower than C r X +.
