摘　　要：Heterobimetallic clusters of Na8Ln(OtBu)10(OH) (Ln = ytterbium, europium, samarium and neodymium) are found to be useful catalysts for amidation of aldehydes with amines under mild conditions. The catalytic activity depends on the central metal ion in the cluster, and the order activity is ytterbium < europium < samarium ≈ neodymium. The catalysts show a wide range of scope in their activity towards amines including aliphatic amines and secondary cyclic amines such as pyrrolidine and piperidine.Heterobimetallic clusters of NasLn（OtBu）10（OH） （Ln = ytterbium, europium, samarium and neodymium） are found to be useful catalysts for amidation of aldehydes with amines under mild conditions.
