Utility of organosamarium(II) reagents in the formation of polyatomic group 16 element anions: Synthesis and structure of [(C{sub 5}Me{sub 5}){sub 2}Sm]{sub 2}(E{sub 3})(THF), [(C{sub 5}Me{sub 5}){sub 2}Sm(THF)]{sub 2}(E), and related species (E = S, Se, Te)

Te and Se react with (C{sub 5}Me{sub 5}){sub 2}Sm(THF){sub 2} to form [(C{sub 5}Me{sub 5}){sub 2}Sm(THF)]{sub 2}({mu}-Te), 1, and [(C{sub 5}Me{sub 5}){sub 2}Sm(THF)]{sub 2}({mu}-Se), 2, respectively. (C{sub 5}Me{sub 5}){sub 2}Sm(THF){sub 2} reacts with Ph{sub 3}P{double_bond}Se and Ph{sub 2}{double_bond}S to form 2 and [(C{sub 5}Me{sub 5}){sub 2}Sm(THF)]{sub 2}({mu}-S), 3, respectively. Larger ratios of Te, Se, and S reacting with (C{sub 5}Me{sub 5}){sub 2}Sm(THF){sub 2} form [(C{sub 5}Me{sub 5}){sub 2}Sm]{sub 2}(Te{sub 3})(THF), 4, and [(C{sub 5}Me{sub 5}){sub 2}Sm]{sub 2}({mu}-{eta}{sup 2}:{eta}{sup 3}Se{sub 3})(THF), 5, and [(C{sub 5}Me{sub 5}){sub 2}Sm]{sub 2}(S{sub 3})(THF), 6. Reactions and X-ray crystal structures of these compounds are discussed.
