  The first Cp ∗ Os half-sandwich complexes containing chalcogenido ligands

  摘要：

  The reactions of the pentamethylcyclopentadienyl-osmium compound Cp*Os(NO)Br-2 (1) with Na2S4 and (NEt(4))(2)Se-6 in dimethylformamide solution lead to mononuclear tetrachalcogenido complexes Cp*Os(NO)(E(4)) (E = S (2a), Se (2b)), whereas binuclear products Cp(2)*Os-2(NO)(2)(mu-E)(2) (E = S (3a), Se (3b), Te (3c)) are obtained from the reactions of 1 with Li(2)E in tetrahydrofuran solution. Dechalcogenation of 2a,b using tri(n-butyl)phosphane gives 3a,b. The molecular geometry of Cp*Os(NO)(Se-4) (2b) has been determined by an X-ray crystal structure analysis which confirms the presence of a non-planar cyclotetraselenido chelate ligand.
