Abstract:
Low temperature magnetization measurements were performed on single crystals of the pyridyl-alcohol-supported [Ni(μ3-Cl)Cl(HL·S)]4 coordination cluster and they revealed open hysteresis loops up to 30mK at a sweep rate of 0.07Ts−1. The studied molecule with intramolecular ferromagnetic coupling Jintra of 15.251K (+10.6cm−1) is an exchange-biased single-molecule magnet that exhibits intermolecular antiferromagnetic coupling Jinter of −0.004K (−0.003cm−1) in the supramolecular environment of four other cubane-type units. Quantum tunneling of magnetization characterized by five steps at −0.1, −0.05, 0, 0.05 and 0.1T was observed.
