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 trinuclear complex with two bridging nitroxides, bis-[μ-(1,2-dihydro-3-oxo-2,2-diphenyl3-H-indole1-1-oxyl)-O; O′]hexakis(hexafluoroacetylacetonato)tricopper(II), which has been structurally characterized by X-ray crystallography. The nitroxide functions of the paramagnetic ligands are coordinated to the terminal copper atoms. Magnetic measurements revealed strong antiferro-magnetic coupling between the spins of the nitroxides and of the terminal copper atoms. © 1993.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
