Abstract

Our main objective is a better understanding of spin- spin interaction of dinuclear copper(lI) complexes through 1t system. The synthesis and characterization of two new dinuclear copper(II) complexes, based on the use of large, pyrole-containing macrocycles, the so called" expanded porphyrins" , [Cu2(macrocycle)]4+ is described. A chloroform solution spectrum of two complexes taken at room temperature and 130-135 K gave a classic electron spin resonance (ESR) pattern for both compounds. Both complexes show a triplet state(S =1), with both ΔM = 1 and ΔM = 2 (half field) transition which is the characteristics of Cu(II)- Cu(II) dimer. The observation of ΔM = 2 band strongly suggests the spin- spin interaction occurs through π system. All compounds exhibit a typical ΔM = 1 transition with superhyperfine splitting due to the 14N bound to copper.
