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.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.
