Transition-metal ions and stable organic radicals, such as the nitroxides, can form clusters containing variable numbers of spins.

Abstract
Transition-metal ions and stable organic radicals, such as the nitroxides, can form clusters containing variable numbers of spins. For instance finite clusters containing from 2 to 12 spins have been reported, as well as infinite arrays2 The nitronyl nitroxides are particularly versatile in giving different arrangements of spins, because they can bind to metal ions in many different ways, i.e. as monodentate ligands to one or two different ions and as bidentate ligands to two different ions. In the present paper we present a copper bis(hexafluoracetylacetonate)nitronyl nitroxides system containing five spin centers. Crystal and molecular structure and the magnetic and EPR properties of such a compound are discussed.File | Dimensione | Formato | |
