Two cyanide-bridged WV-M [M = MnIII (1), Co II (2)] bimetallic clusters were prepared by self-assembling a new molecular precursor [W(CN)6(bpy)]- and the corresponding metal complexes. Compound 1 shows a tetranuclear W2Mn2 entity, consisting of a Jahn-Teller ion, MnIII, which serves as an anisotropic source, while compound 2 exhibits a trimeric W2Co structure. Among them, compound 1 displays slow relaxation of the magnetization, which is typical of a single-molecule magnet behavior.
