Abstract
The complex [Fe(bzimpy) 2] (BPh 4) 2 · nH 2O exists with n = 4 ( 1), n = 2 ( 2) and n = 0 (3). The tetrahydrate is a spin crossover system with the transition centred at room temperature. The dihydrate, prepared from a solution with reduced water content, is a high-spin complex over the entire temperature region. The anhydrous complex, prepared by overheating of 1, remains high-spin. Unlike that in the sulphate ( 4) and perchlorate ( 5) analogues, the spin crossover in 1 is complete. The magnetic data fitting procedure yields the set of magnetic parameters describing the spin crossover quantitatively: g = 2.54, J/k= − 226K, Δ H = 14.9kJ mol −1 and ΔS = 45J K −1mol −1.
