A series of five isostructural tetranuclear defect dicubane, or butterfly, topology 4f coordination clusters of formula [LnIII4(μ3-OH)2(L)4(HL)2]·2THF, [H2L = (E)-2-(2-hydroxy-3-methoxybenzylideneamino)phenol; Ln = Gd(1), Tb(2), Dy(3), Ho(4) and Er(5)) has been synthesized and characterized. The highly anisotropic Dy4 and Ho4 complexes clearly show intramolecular ferromagnetic coupling which arise from dominant intramolecular dipolar–dipolar interactions rather than any significant superexchange effects. Furthermore, the Dy4 complex shows Single Molecule Magnet (SMM) behavior.
