Abstract:
A series of macrobicyclic binuclear iron(II) oximehydrazonates has been synthesized by encapsulation of preliminary obtained non-macrocyclic tris-complexes with boron- and tin-containing Lewis acids and direct template reactions on the Fe2+ ion. The structures of the synthesized compounds have been studied using IR, electronic, polynuclear (1H, 13C, 11B, 119 Sn) NMR, Mössbauer (57Fe, 119Sn) and EXAFS spectra. The trigonal-prismatic and trigonal-antiprismatic geometry of the Fe2+ coordination polyhedron for boron- and tin-containing clathrochelates, respectively, has been established from Mössbauer (57Fe) parameters. The Fe-N distances ( ∼ 1.9 Å), typical for macrobicyclic azomethine iron(II) complexes, and intramolecular Fe...Fe ( ∼ 3.90 Å) and Fe...Sn ( ~ 3.80 Å) distances have been obtained from EXAFS spectra. Cyclic voltammograms of synthesized binuclear compounds have demonstrated the formation of unstable mixed-valence Fe2+-Fe3+ complexes by oxidation.
