| Abstract: | Complex formation in the systems containing copper(II), cobalt(II) and nickel(II) ions (M) and 3-(3,5-dimethylpyrazol-1-yl)-6-R-1,2,4,5-tetrazines (R = 2-hydroxyethylamino, piperidino) (L) was studied by voltammetry and spectrophotometry. Cu(II), Co(II) and Ni(II) were found to form complex compounds with derivatives of 1,2,4,5-tetrazine with the ratio of the components M:L = 1:1. The complex stability constants were determined. |
