Abstract

A family of planar disc-like hexa-, octa- and decametallic NiII complexes exhibit dominant ferromagnetic exchange. The deca- and octametallic clusters [NiII10(tmp)2(N3) 8(acac)6(MeOH)6] (1, H3tmp = 1,1,1-tris(hydroxymethyl)propane; acac = acetylacetonate) and [Ni II8(thme)2(O2CPh) 4(Cl)6(MeCN)6(H2O)2] (2, H3thme = 1,1,1-tris(hydroxymethyl)ethane) represent rare examples of NiII-based single-molecule magnets, and [NiII 10] (1) possesses the largest barrier to magnetisation reversal of any NiII single-molecule magnet to date. © 2009 Wiley-VCH Verlag GmbH & Co.
