Abstract: The cyclic voltammetric behavior of ⅥBcarbonyl complexes containing bis(pyrazol-1-yl)alkanes has been investigated. It was found that the redox potentials(E1/2) of metal centers remarkably relate to the ability of electron donating of ligands. Metal centers with electron donating groups on the pyrazolyl rings are easier to be oxidized than those containing electron withdrawing groups.

Key words: Bis(pyrazol-1-yl)alkane, ⅥB metal carbonyl complexes, Cyclic voltammetry
