Synthesis of cubane-type Ni(II) complexes from pyridyl-alcohol ligands; their single-molecule magnet behaviour.


The reactions of NiCl2·2H2O or [NiCl2(DME)] (DME = dimethoxyethane) with 2-methyl-1-(pyridin-2-yl)propan-2-ol (HL) and 2-(pyridin-2-yl)ethanol (HLEt), in a 1:1 ratio, afforded the tetranuclear, cubane-type clusters [Ni(μ3-Cl)Cl(HL)]4 (3) and [Ni(μ3-Cl)Cl(HLEt)]4 (4), respectively. These are tetramers of the hypothetical mononuclear formula-isomers [NiCl2(HL… (More)
