One-Dimensional Mn(III) Coordination Polymer Exhibiting Ferromagnetic Coupling

Mn(III) complexes of 1-(2-hydroxybenzamido)-2-((2-hydroxy-3-methoxybenzylidene)amino)ethane (H₃L), mononuclear [Mn(L)(MeOH)(H₂O)] (1) and amido-bridged one-dimensional [Mn(L)(H₂O)]_∞ (2), have been synthesized by the reaction of MnAc₃·2H₂O with H₃L. Magnetic studies revealed that complex 2 exhibits intermetallic ferromagnetic coupling, which is the first one-dimensional high-spin Mn(III) complex with ferromagnetic behavior.
