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 (Mn2M2II)-M-III} complexes (M-II = Mn, 2; Ni, 3). Magnetic measurements show that 1-3 exhibit S-T = 1, 3, and 4 spin ground states, respectively.
