A strategy for new macrocycle magnetic materials synthesis
A study of a series of new types of copper(II) and rhenium(IV) macrocyclic complexes, important macrocyclic molecular magnets, is reported. A detailed description of crystal structure and magnetic behavior of mononuclear copper(II) macrocyclic compounds: CuL1(ClO4)2 (L1 = N-d-2,4,4,9,11,11-hexamethyl-1,5,8,12-tetraazacyclotetradeca-2,9-diene), CuL2(ClO4)2 (L2 = N-d-7,14-diisopropyl-5,12-dimethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene) and of heteropolynuclear complexes: [CuL1][ReCl4(ox)] · DMF and [(CuL2)(ox)ReCl4] is presented. The results indicate that all compounds behave as weak interacting magnets.
