Abstract
Coordination-induced chirality was achieved in a uniquetetrahedral [Dy 4(μ 4-O)(μ-OMe) 2(beh) 2(esh) 4]·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).
