A new versatile class of hetero-tetra-metallic assemblies: highlighting single-molecule magnet behaviour

Hetero-tetra-metallic species based on hexanuclear assemblies [((valen)M1)Ln(OH2)2(μM2(CN)8)]22− (Ln = GdIII, TbIII; M1 = CuII, NiII and M2 = MoIV, WIV) and co-crystallized mononuclear complexes [M3(tpy)2]2+ (M3 = NiII, RuII, OsII) were identified, fully characterized, and shown to constitute a new class of single-molecule magnets.
