文摘

Treatment of tris(3-cyano-2,4-pentanedionato)manganese(III) with KTp*, followed by [NEt₄]CN affords [NEt₄][(Tp*)Mn^III(CN)₃] (1); subsequent treatment of 1 with divalent triflates (OTf) and 2,2′-bipyridine (bpy) affords {Mn^III₂M^II₂} complexes (M^II = Mn, 2; Ni, 3). Magnetic measurements show that 1−3 exhibit S_T = 1, 3, and 4 spin ground states, respectively.
