with two butterfly-like [Cu4(μ4-O)(μ3-OH)] subunits. The magnetic properties of these three complexes were characterized by the measurements of variable-temperature and field magnetic susceptibility. The magnetic analysis showed that a strong antiferromagnetic interaction was mediated between Cu(II) ions by the single OH− bridge in 1 and resulted a S = 3/2 spin ground state. In complex 2, both intramolecular
