In this paper we report a new model aimed at the explanation of the magnetic properties
of the trigonal bipyramidal cyanide cluster - [MnII
(tmphen)2]3[MnIII
(CN)6]2} (tmphen =
4,5,7,8-tetramethyl-1,10-phenantroline). The model explicitly takes into account the strong
single-ion anisotropy associated with the unquenched orbital angular momenta of two Mn(III)
ions, and satisfactory explains the observed temperature dependence of dc magnetic
susceptibility. At the same time the model is compatible with firmly confirmed fact that the
system represents single molecule magnet and provides the theoretical background for the
design of new cyanide-based single molecule magnets with higher blocking temperatures. |
