摘要：

Six new tetra- or pendentate, N-phenolate functionalized, pendant arm macrocyclic ligands containing a 1,4,7-triazacyclononane or a 1-oxa-4,7-diazacyclononane backbone have been synthesized and their coordination chemistry with iron(III) has been investigated. Electronic spectra of these octahedral high-spin Fe(III) complexes have been measured. The phenolate-to-iron(III) charge transfer band has been studied as a function of the number of coordinated phenolate residues (1, 2 or 3) and of the substituents at the phenolate arms. The dinuclear complex [L27Fe2(mu-O2CPH)](ClO4)3 has been synthesized where the two Fe(III) centres are connected via a symmetric mu-benzoato bridge and two phenolate oxygen atoms (L7 = N-(2-hydroxybenzyl)-1,4,7-triazacyclononane).
