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).
