Role of orbitally degenerate Mn(III) ions in magnetic bistability of Mn5-cyanide cluster: new prospects for design of single molecule magnets with high blocking temperatures

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...
