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)] x H2O (2), and a one-dimensional zigzag chain, [Fe(mpzcq)(CN)3][Mn(salcy)] x MeOH x MeCN (3). Antiferromagnetic couplings are operating between magnetic centers through CN ligands, and a field-induced metamagnetic transition is observed in 3.
