Abstract

The reaction of MnCl₂·4H₂O (1 equiv), salicyladoxime (H₂salox) (1 equiv), and NaN₃ (1 equiv) in MeOH with NEt₄OH (1 equiv) gave (NEt₄)₃[Mn₅O(salox)₃(N₃)₆Cl₂] (2) in ∼14% yield. Ferromagnetic exchange between the five Mn ions in 2 leads to an S = 11 ground state and is established as a new single-molecule magnet with an anisotropy energy, Ueff, of 40.3K by frequency dependent out-of-phase alternating current susceptibility signals and temperature and sweep rate dependent hysteresis loops.
