SYNTHESES AND MAGNETIC PROPERTIES OF N-[2-(2-HYDROXYETHYLTHIO)PHENYL]ARENESULFONAMIDATOCOPPER(2) CHELATES

Various N-[2-(2-hydroxyethylthio)phenyl]arenesulfonamidatocopper(II) chelates and the addition compounds thereof with methanol or ethanol were synthesized, and several typical ones were subjected to magnetic determination at temperatures between about 80 and 300°K. The temperature dependence of the observed magnetic susceptibility indicates that the copper(II) chelate-bisalcohols form dimeric aggregates while the alcohol-free copper(II) complexes are trimeric when they are prepared by precipitation from chloroform solutions and heating in n-hexane rather than by heating the copper(II) chelate-bisethanol or -bismethanol under reduced pressure. The molecular weights of the alcohol-free complexes also are indicative of the existence of trimeric molecules in chloroform solutions. © 1968, American Chemical Society. All rights reserved.
