Abstract: A tetranuclear cyanide-bridged (Fe2Ni2II)-Ni-III cluster [Fe-III(Tp)(CN)(3)](2)Ni-2(II)(4,4'-dibromo-2,2,-bpy)(4)center dot 2ClO(4) (1) (Tp = hydrotris(pyrazolyl)borate) was synthesized. Magnetic measurements indicated that this compound displayed single-molecule magnet behavior with the pre-exponential factor of tau(0) = 1.79(8) x 10(-10) s and the relaxation energy barrier of Delta/k(B) = 65.1(9) K.
