An S=2 cyanide-bridged trinuclear (Fe2NIII)-N-III single-molecule magnet
Treatment of [NEt4][(pzTp)Fe-III(CN)(3)] (1) with Ni-II(OTf)(2) (OTf = trifluoromethanesulfonate) and 1,5,8,12-tetraazadodecane (L) affords {[(pzTp)Fe-III(CN)(3)](2)[(NiL)-L-II]}center dot(1)/2MeOH (2), while 2,2'-bipyridine (bipy) affords {[(pzTp)Fe-III(CN)(3)](2)[Ni-II(bipy)(2)]}center dot 2H(2)O (3). Magnetic measurements indicate that 2 and 3 have S = 2 ground states and that 3 exhibits slow relaxation of the magnetization above 2 K.
