Lanthanides chalcogenolates

FIGURE 65 Common structural types of lanthanide chalcogenolate and chalcogenide clusters with nuclearity ranging from six to eight (redrawn after Li et al., 2006a). 

The aim of this chapter is to review the chemistry of chalcogenolates in the last 10 years. The more recent reviews in this field included chalcogenolates of the s-block elements,13,14 early transition metal thiolates,15 metal complexes with selenolate and tellurolate ligands,16 copper(I), lithium and magnesium thiolates,17 functionalized thiolate complexes,18 19 pentafluorobenzenethiolate platinum group compounds,20 tellurium derivatives,21 luminescent gold compounds,22 and complexes with lanthanide or actinide.23... 

Mixed alkali-metal chalcogenolates have been synthesized for main group elements, such as aluminium,54,55 germanium, and tin as (6) (Scheme 2),56 or transition metals such as zirconium,57 60 iron,61,62 vanadium,63 nickel,64 rhenium,65 and cobalt,66 or lanthanide metals.67,68... 

In order to probe the chemistry of the electronically important Eu ion, resonance-stabilized thiolates were explored. Of the simple chalcogenolates, only the pyridinethi-olate (S-2-NC5H4, SPy) ligand has been used successfully in Eu(III) chemistry. Compounds with SPy have been prepared across the lanthanide series, and again there is a tendency for the larger Ln to form more complicated species, while the smaller Ln readily form discrete uncharged species. Most significant here is the chemistry of Eu, for which divalent...
