The magnetic behavior as a function of temperature has been determined for a number of binuclear copper(II) complexes with Schiff's bases derived from the condensation of substituted and unsubstituted salicylaldehydes with substituted and unsubstituted o-aminophenols. The magnetic properties are markedly affected by the nature and the position of the substituent on the chelate ring. Only one compound exhibited simple copper acetate like behavior. The data for the other compounds indicated that the systems were complicated by the presence of isomers and by inter- as well as intramolecular interactions. The spectra of selected compounds were studied as a function of temperature. There was no significant effect on either band position or intensity.
