The reaction of tBuNH2 with a mixture of SeCl2 and SeOCl2 in a 6: 2: 1 molar ratio produces the novel selenium-nitrogen chain ClSeN(tBu) Se(O) Cl (4), in which the selenium atoms are in two different oxidation states, Se-II and Se-IV. The crystal structure of 4 is compared with that of the related Se-II/Se-II system ClSeN(tBu) SeCl (1) and differences are attributed to hyperconjugative effects. The energetics of the formation of 4 via two different routes are elucidated by PBE0/def2-TZVPP calculations.
