1∶1 Complexes of 5-(4-[N-tert-butyl-N-aminoxyl]phenyl)pyrimidine with manganese(ii) and copper(ii) hexafluoroacetonylacetonate†
Abstract
Mn(hfac)2 and Cu(hfac)2 form 1∶1 complexes with 5-(4-[N-tert-butyl-N-aminoxyl]phenyl)pyrimidine that exhibit strong metal–nitroxide exchange; spin polarization models do not explain the antiferromagnetic exchange behavior between spin sites in these complexes.
