Kl. Bieda et al., SYNTHESIS AND CHARACTERIZATION OF IRON CLATHROCHELATE COMPLEXES DERIVED FROM OXIME HYDRAZONE LIGANDS AND CAPPED BY FERROCENYLBORATE AND 1,1'-FERROCENEDIYLDIBORATE, Inorganic chemistry, 32(20), 1993, pp. 4209-4213
The synthesis and characterization of a series of iron clathrochelate
complexes based on oxime-hydrazone ligands and capped with ferrocenylb
oronic acid to produce dimetallic species is reported. The first examp
le of a metal complex which uses 1,1'-ferrocenediyldiboronic acid as a
capping/bridging agent between two clathrochelate complexes to form a
novel trimetallic species is also presented. The redox chemistry of t
hese multiple metal systems is examined by cyclic voltammetry and cont
rolled-potential electrolysis. The generation of stable mixed-valent (
Fe2+/Fe3+) species by exhaustive electrolysis and their subsequent cha
racterization by UV-visible spectroscopy and cyclic voltammetry is dis
cussed.
