Field-Induced Metamagnetic Transition in the Fe^III−Mn^III Bimetallic Chain Built by a New Cyanide-Bearing Fe^III Precursor

The use of a new precursor, mer-[Fe(mpzcq)(CN)3]- (1), produced a dimeric molecule, [Fe(mpzcq)(CN)3][Mn(salen)(H2O)]·H2O (2), and a one-dimensional zigzag chain, [Fe(mpzcq)(CN)3][Mn(salcy)]·MeOH·MeCN (3). Antiferromagnetic couplings are operating between magnetic centers through CN ligands, and a field-induced metamagnetic transition is observed in 3.
