Synthesis and Characterization of Novel Lanthanocene Complexes with Dichalcogenolate o‐Carboranyl Ligands

Abstract

AbstractReactions of [Cp2Ln(μ‐Cl)]2 (Cp= η5‐C5H5, Ln = Nd, Yb, Dy, Gd, Er) with an equivalent of [(THF)3LiE2C2Bi0H10Li. (THF)]2 (E= S, Se) in THF afforded the dinuclear sandwich complexes of formula [CP2LnE2C2B10H10]2[LI(THF)4]2[E = S, Ln=Nd (1a), Yb (2a), Dy (3a), Gd (4a), Er (5a); E=Se, Ln=Nd (1b), Yb (2b), Dy (3b), Gd (4b), Er (5b)]. The molecular structures of complexes la, 2a and 2b were determined by the single crystal X‐ray structure analyses. Two lanthanide atoms are connected by a pair chalcogen (η1, η2‐E2C2B10H10) bridging ligands and the central Ln2E2 four membered ring is not planar.
