The possibilities of the ion exchange reactions between the neodymium(III) and samarium(III) diiodo-β-diketiminate complexes [Ln(Nacnac)I2(Тhf)2] (Ln = Nd (I), Sm (II); Nacnac is (Formula presented.) Thf is tetrahydrofuran) and potassium mono- and dichalcogenides K2Qn (Q = S, Se, Te; n = 1, 2) in Thf are studied. The ion exchange of iodide ligands by dichalcogenide ligands does not occur under these conditions. The reaction of complex I with K2Se affords the divalent samarium complex [Sm(Nacnac)I(Thf)2] (III). The sequence of the steps leading to the formation of this complex, including the reduction of the sterically hindered bis(diketiminate) complex, is proposed.
