Abstract

Using K3Mn(CN)6, DMF and Ln(NO3)3 · 6H2O (Ln = Tb, Dy or Er), novel cyano-bridged complexes Ln(DMF)4(H2O)2Mn(CN)6 · H2O (TbMn, DyMn and ErMn, respectively) were prepared and their magnetochemical properties were studied in detail. A weak antiferromagnetic interaction was found to exist between the rare earth ions and the manganese ion. Er(DMF)4(H2O)2Mn(CN)6 · H2O, in particular, exhibits long-range magnetic ordering, a higher critical temperature (T c = 17.5 K) and a stronger coercive force (H c = 980 Oe).
