Electrochemical and Electrocatalytic Characteristics of Coordination Polymers Based on Trinuclear Pivalates and Heterocyclic Bridging Ligands

It was shown by cyclic voltammetry that the coordination polymers [Fe2NiO(Piv)6(L)x]n, where L is a ligand containing a 1,2,4,5-tetrazine or thiazolothiazole fragment, Piv – is pivalate, and x = 1 or 1.5, possess redox activity in the solid form when deposited on an inert electrode, and the redox potentials of the transitions correlate with the corresponding redox potentials of the ligands in solutions. The coordination polymer containing bis(4-pyridyl)thiazolothiazole catalyzes the electrochemical dehalogenation of CF3CHClBr with the formation of CF2=CHCl and CF3CH2Cl.
