• The formation of thiocyanate complexes of cadmium (II), copper(II), cobalt(II), and iron(II) has been studied in acetonitrile by polarographic, conductometric, and spectrophotometric methods. The values of overall stability constants were found to be; logβ<SUB>4</SUB>=19.7 for [Cd(SCN)<SUB>4</SUB>]<SUP>2−</SUP>, logβ<SUB>2</SUB>=7.6 for [Cu(SCN)<SUB>2</SUB>]<SUP>−</SUP> and logβ<SUB>4</SUB>=15.5 for [Co(NCS)<SUB>4</SUB>]<SUP>2−</SUP>. The reaction between copper(II) species and mercury metal was investigated and the electrode reaction was estimated. Kinetic current for cobalt(II)-thiocyanate complex was observed and the rate constant for the dissociation of the complex was obtained. The rate constant of reduction in the iron(II)-thiocyanate system was determined to be 1.9×10<SUP>−3</SUP> cm/s by cyclic voltammetry.
