| Abstract: | Cu(hfac)2 chain polymer heterospin complexes with pyrazole-substituted nitronylnitroxides (LR, where R = Me, Et) with a composition Cu(hfac)2LR, exhibiting structural rearrangements with magnetic effects in the solid state at reduced temperatures, were studied by magnetic resonance. The magnetic resonance spectrum changes substantially for substituents of different types. The results of this study are discussed in the context of the cluster approach in view of the specific crystal structure of the compounds. |
