摘要：

Treatment of [Mn4O2(OAc)(6)(py)(2)(dbm)(2)] 1 (py = pyridine, Hdbm = dibenzoylmethane) in hot MeCN with Me(3)SiX (X = N-3-, OCN-) yields [Mn(4)O(3)X(OAc)(3)(dbm)(3)] containing extremely rare eta(1), mu(3)-N-3- or -OCN- groups; alternating-current magnetic susceptibility studies reveal unusual magnetic relaxation effects and indicate these species to be the newest and smallest examples yet of truly molecular magnets.
