Abstract
N-Benzyloxycarbonyl-substituted amino acids (HL) react with the copper(II) ion to form simple green complexes of formula [{CuL2(H2O)n}2](L =N-benzyloxycarbonyl-glycinate, -valinate, or -leucinate, n= 1; L =N-benzyloxycarbonylalaninate, n= 0), which show physical properties indicating a dimeric structure with strong antiferromagnetic interactions between the copper(II) ions within the pairs through a superexchange mechanism via bridging carboxylate groups. Exchange integrals (–2J) in the range 295–350 cm–1 were calculated.Keywords
