Previously unknown 3,4-diamino-1,2,5-selenadiazole (6) was prepared by hydrolysis of [1,2,5]selenadiazolo[3,4-c][1,2,5]selenadiazole (7b) and used in synthesis of novel 1,2,5-selenadiazolo[3,4-b]pyrazines by the Koerner-Hinsberg reaction covering the parent compound 4 and its substituted derivatives 5a-g. The compounds synthesized were characterized by solution and solid-state Se-77 NMR, and 6, 5-Ph and 5,6-Me-2[1,2,5]selenadiazolo[3,4-b]pyrazines (5a, g, respectively) by X-ray diffraction. Electrochemical reduction of 5,6-R-2[1,2,5]selenadiazolo[3,4-b]pyrazines 5c, g (R = Ph, Me) into novel persistent radical anions (RAs) was studied by cyclic voltammetry and the RAs [5c](-) and [5g](-) were characterized by EPR spectroscopy combined with DFT calculations.
