Abstract

The dimers {(^tBuC₅H₄)₂,Ln(μ-Me)}₂ (LnY, or Lu) react with organic dichalcogenides R₂E₂ (ES or Se; RPh, ⁿBu, ^tBu or CH₂Ph) to form {(^tBuC₅H₄)₂Ln(μ-ER)}₂ complexes with LnS or LnSe bonds. The molecular structure of {(^tBuC₅H₄)₂Ln(μ-SePh)}₂·C₆H₆ has been determined by X-ray diffraction ( $P$ ; a = 11.242(2) Å, b = 11.388(2) Å and c = 12.865(2) Å; α = 110.32(2)°; β = 105.16(2)°; and γ = 102.84(2)°; Z = 1; d_calc. = 1.343 g cm⁻³; R = 0.0509 and R_ω = 0.0532). The two yttrium atoms of the centrosymmetric dimeric molecule are bridged by two μ-SePh groups.

Lanthanide chalcogenolate complexes: Syntheses, structures and applications in organic chemistry
2006, Coordination Chemistry Reviews
The chemistry of lanthanide chalcogenolate complexes has expanded dramatically in the recent years. This review summarized the syntheses and crystal structures of the lanthanide chalcogenolate complexes and their applications in organic chemistry. Four methods for the synthesis of lanthanide chalcogenolate complexes were outlined: protonolysis, metathesis, oxidation–reduction, and insertion reaction. The lanthanide chalcogenolate complexes were classified according to the ancillary ligands coordinated to lanthanide atoms and the number of lanthanide atoms, and some specific structures were briefly described. The reactivity and catalytical property of some lanthanide chalcogenolate complexes in organic and polymer synthesis along with their luminescent properties are highlighted.

Lanthanide series is because of the successive filling of the 4f orbitals, it is generally assumed that they do not contribute significantly to bonding because of their limited radial extension and the shielding from the valence shell by the filled 5s and 5p orbitals. However, these f-orbitals (filled or empty) should be able to modulate some electronic properties of the metal center. In the ubiquitous oxidation state 3+, the lanthanide ions reach an inert gas core configuration by the loss of one 4f electron. It is for this reason that yttrium and scandium complexes are included in discussions of lanthanide chemistry. The chemical differences between lanthanide and actinide derivatives are mainly because of some differences in their electronic structures. The 5f orbitals of early actinides are incompletely shielded from external influences by the 6s and 6p electrons, thus they have sufficient radial expansion for some overlap with ligand orbitals. The chapter also discusses the main classes of organolanthanides and organoactinides.

Reaction of Cp₃Yb (Cp = C₅H₅) with equimolar n-propane thiol in THF at room temperature resulted in the formation of the new complex [Cp₂Yb(μ-SCH₂CH₂CH₃)]² in good yield, which was characterized by elemental analysis and mass spectra, and studies by X-ray crystallography. The title complex crystallized from the saturated THF solution in dimeric form with thiolate ligands as bridging groups. The bridging unit Yb₂S₂ is planar. The ytterbium atom was coordinated by two Cp groups and two bridged sulfur atoms to form a distorted tetrahedral geometry. The Yb—C(Cp) bond distances range from 2.48(2) to 2.71(2) , averaging 2.60(2) . The Yb—S bond lengths range from 2.69(7) to 2.71(8) , averaging 2.705(8) . Copyright © 1996 Elsevier Science Ltd
