Supramolecular 3d-4f single-molecule magnet architectures

Dalton Trans. 2016 Oct 18;45(41):16148-16152. doi: 10.1039/c6dt03392j.

Abstract

The nanosized self-assemblies {[{LnIII}{H2O⊂CrLn}]2(H2O)} (Ln = Dy, 1 and Tb, 2) based on new 3d-4f mixed-metal coordination topologies are formed via extensive intramolecular hydrogen bonding that is directed by enclosed water molecules. Compounds 1 and 2 show single-molecule magnet characteristics manifested by hysteresis loops up to 1.6 K (Ueff = 8.3 cm-1) and 1 K (Ueff = 3.4 cm-1), respectively.
