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 30 mK at a sweep rate of 0.07 T s−1. The studied molecule with intramolecular ferromagnetic coupling Jintra of 15.251 K (+10.6 cm−1) is an exchange-biased single-molecule magnet that exhibits intermolecular antiferromagnetic coupling Jinter of −0.004 K (−0.003 cm−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 0.1 T was observed.
