Abstract
An exchange interaction was found between copper ions when bromide ions were added to a solution of copper bis-acetylacetonate in methylene chloride. The magnetic moments as well as the electronic and ESR spectra of these solutions were measured. The magnetic moment, exchange integral (− J) and D value show that the type of mechanism through which the exchange coupling occurs is superexchange via a bromide bridge. The assignment of the changed electronic spectrum is discussed.
