Abstract

Di- and trinuclear transition metal complexes were obtained by the reaction of ferrocenyl substituted pyrazolyl pyridines with Mo(CO)4(pip)2 (pip = piperidine, 5). The structure of the dinuclear complex tetracarbonyl{[5-ferrocenyl-3-(2-pyridyl)-1-pyrazolyl]aceticacidethylester}molybdenum(0), 6a, was determined by X-ray structure analysis. The redox properties of the complexes were characterized by cyclovoltammetry. The shifts in reversible potential, observed when the molybdenum tetracarbonyl and ferrocene moieties are attached to the ligand system, were consistent with changes observed in spectroscopic parameters.
