I t was established by the method of voltammetry that the mixed ligand complex [BiEdtaSCN] 2 - is electrochemically active form in solution, containing thiocyanate- and ethylenediaminetetraacetate -ions. The discharge of this complex occurs at a slower rate as compared with the discharge of the complex [BiEdta] - in ethylenediaminetetraacetate solution . The kinetic parameters of the cathodic process with the participation of the [BiEdta] - and [BiEdtaSCN] 2 - were determined. The explanation for the difficulties of [BiEdtaSCN] 2 - discharge was suggested on the basis of the analysis of lowest unoccupied molecular orbital composition of the considered complexes .
