A Rare μ4-O Centred Dy4 Tetrahedron with Coordination-Induced Local Chirality and Single-Molecule Magnet Behaviour

Coordination-induced chirality was achieved in a unique tetrahedral [Dy-4(mu(4)-O)(mu-OMe)(2)(beh)(2)(esh)(4)]center dot 3MeOH complex through a twisted diazine bridge from a Schiff base ligand. Magnetic measurements reveal weak intramolecular antiferromagnetic interactions (J = -0.3 cm(-1)) with single-molecule magnet behaviour (U-eff = 23.42 K).
