Abstract
Copper hexafluoroacetylacetonate reacts with an indole nitroxide (1,2- dihydro-3-oxo-2,2-diphenyl-3H-indole-1-oxyl) in hexane to yield a trin uclear complex with two bridging nitroxides, ,2-dihydro-3-oxo-2,2-diph enyl-3H-indole-1-oxyl)-O; ]hexa-kis(hexafluoroacetylacetonato)tricoppe r(II), which has been structurally characterized by X-ray crystallogra phy. The nitroxide functions of the paramagnetic ligands are coordinat ed to the terminal copper atoms. Magnetic measurements revealed strong antiferromagnetic coupling between the spins of the nitroxides and of the terminal copper atoms.
