First Structurally Characterized Tricyanomanganate(III) and its Magnetic {MnIII 2MII2} Complexes (MII = Mn, Ni)
Résumé
Treatment of tris(3-cyano2,4 pentanedionato)manganese(III) with KTp*, followed by [NEt4]CN affords [NEt4][(Tp*)MnIII(CN)3](1); subsequent treatment of 1 with divalent triflates (OTf) and 2,20- bipyridine (bpy) affords {MnIII 2MII2} complexes (MII = Mn, 2; Ni, 3). Magnetic measurements show that 1-3 exhibit ST = 1, 3, and 4 spin ground states, respectively.
