The synthesis of the selenium-based ligand L1SeSeL1 (2,2’-diselanediylbis(N,N-bis(pyridin-2-ylmethyl)ethan-1-amine) is described along with its reactivity cobalt(II) salts. cobalt(II)-diselenide complex [Co2(L1SeSeL1)Cl4] was obtained in good yield, and spectroscopic properties closely resemble that sulfur analog. Reaction Co(II) thiocyanate results formation cobalt(III) compound [Co(L1Se)(NCS)...
