thermal decomposition of 5, and ligand 1 was recovered quantitatively. However, in the presence of excess amount of Fe2(CO)9 in refluxing acetonitrile, complex 5 was converted into 2–4. On the other hand, the reaction of N-(6-methyl-2-pyridylmethylidene)-2-thiolethylamine (6) with Fe2(CO)9 in refluxing acetonitrile produced 2, μ-[N-(6-methyl-2-pyridylmethyl)-η1 (Npy);η1:η1(N); η1:η1(S)-2-thiolatoeth
