The change of the X atom to Br in Br·H2O results in the FeII sites being decoupled due to halogen atom steric bulk, resulting in the independent spin-state transition of Fe1 and Fe2 sites and a two-step spin-state transition pathway. Uniquely, all three possible spin-state transition pathways of a two-site switching system are observed in this family [(1) HS-HS ↔ HS-LS ↔ LS-LS for Br·H2O, (2) HS-HS ↔ LS-HS ↔ LS-LS for F·3H2O, and (3) HS-HS ↔ LS-LS for Cl·H2O for Fe1-Fe2]. Overall, these findings broadly support recent theore
