The copper complex of 3-phenyl-l,2,3>4-thiatriazolium-5-thiolate was patented to form the metal layer adhering to... 

The two thiolate-bridged nickel-copper complexes in Fig. 6.6 have been prepared by reaction of [N2S2]Ni-type complexes with [Cu(CO)(PhTtBu)], the latter available via the carbonylation of [Cu(MeCN)(PhTt Bu)]. These complexes can be employed as model for the catalytic site of the acetyl coenzyme A synthase.14...

In type IV, the thiolate sulfur atom coordinates to a metal atom and the thiocarbonyl sulfur coordinates to another metal atom. This type of coordination is seen in tetrathiooxalate complexes (see Sect.2.7) [21-30].This coordination style is also seen in polynuclear silver and copper complexes [31,32]. 

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,early transition metal thiolates,metal complexes with selenolate and tellurolate ligands, copper(I), lithium and magnesium thiolates,functionalized thiolate complexes,pentafluorobenzenethiolate platinum group compounds, tellurium derivatives, luminescent gold compounds, and complexes with lanthanide or actinide. ... 

Ford and Vogler reported the photophysical properties of a hexanuclear copper(I) thiolate cluster [Cu (mtc) ] (13) and the related silver(I) complexes [86]. The copper complex shows an intense emission band at 706 nm (Xo = 0.99 ps) and 767 nm (Xq = 14.0 ps) in the solid state at 294 and 77 K, respectively. The emissive state has been suggested to derive from an admixture of LMCT [thiolate Cu ] and metal-centered d-s character. 

Closely related are vanadium-copper complexes [VCu4(p -S>4(S2CN C4HgO)4 (SPh) ] n = 1-3) (Fig. 236), in which copper centers are linked by sulfido bridges to vanadium, and each copper carries either a dithiocarbamate or thiolate ligand (700,1747,1748). Vanadium-51 NMR studies suggest that in solution the different complexes are in equilibrium with one another.
