Abstract
Iron(III) complexes with potentially hexa- and heptadentate oligothioether salicylaldiminates were synthesized. Electron spin resonance and M & ouml;ssbauer spectra reveal the existence of spin crossover effects between 77 and 300 K. The compounds exhibit solvatochromic behaviour. Their cyclic voltammetry shows reversible one-electron electrochemical processes attributed to the iron(III)/iron(II) couple, while insertion of the additional (ether or thioether) donor atom into the ligand structure causes an anodic shift of the E1/2, the thioether sulfur-atom substantially so. Evidence is presented for heptacoordination in the unique complex entailing the unusual heptadentate N2O2S3 donor set.
