摘要：

Slow relaxation of the magnetization reveals the single-molecule magnetic behavior of [Mn2(saltmen)2(ReO4)2] (saltmen2- = N,N′-(1,1,2,2-tetramethylethylene) bis(salicylideneiminate), a simple, out-of-plane MnIII dimeric complex containing a [MnIII(μ-O)2MnIII] core (see structure shown, Mn brown, O red, N blue, Re pink). The two anisotropic MnIII ions are ferromagnetically coupled, which induces an S T = 4 ground state.
