摘要
The syntheses, crystal structures and magnetic properties of two cyano-bridged heterobimetallic compounds prepared from a paramagnetic Ru^Ⅲ building block, transK[Ru^Ⅲ(salchda)(CN)2](1, salchda = N,N'-bis(salicylidene)-o-cyclohexylenediamine), are described.1 reacts with hydrated CoCl2 and [Mn Ⅲ(salchda)(Cl)(H2O)] in MeOH to produce a trinuclear compound {[Ru^Ⅲ(salchda)(CN)]2(μ-CN)2[Co(MeOH)4]·4MeOH}n(2) and a dinuclear{[Ru^Ⅲ(salchda)(CN)](μ-CN)[Mn^Ⅲ(salchda)(MeOH)]·2MeOH}n(3), respectively. Both compounds exhibit intramolecular ferromagnetic coupling between Ru^Ⅲ and 3-d metal centers via the cyano bridge and intermolecular antiferromagnetic coupling. Moreover, 2 exhibits antiferromagnetic ordering below 3.4 K.
