Abstract

The new cyanido-bridged mixed valent FeII/CoIII macrocyclic complexes [L 2 CoIII(-NC)FeII(CN)5] and trans- [L 2 CoIII(-NC)FeII(CN)4(-CN)CoIIIL 2 ]2+ have been prepared and characterized spectroscopically. The trinuclear complex trans-[L 2 Co(-NC)Fe(CN)4(-CN)CoL 2 ](ClO4) 211H2 O has been characterized crystallographically. The diand trinuclear complexes exhibit metal-to-metal charge transfer transitions characteristic of Class II mixed valent chromophores and their redox and spectroscopic properties have been analyzed by Hush theory. The thiophene group attached to the macrocycle L 2 in these complexes may serve as a precursor to conducting polythiophene-based hybrid materials incorporating redox active transition metal ions.
