Various bidentate ligands like dithiocarbamate afford monomeric square planar complexes specific examples are Pt(S2CNEt2)2 and Pt(Se2CNBu)2 (confirmed by X-ray). A similar structure is found for the dithiobenzoate Pd(S2CPh)2 one form of the dithioacetate is dimeric, a second form is a mixture of monomers and dimers.

Eventually we formed carbonyls in the liquid phase by redox disproportionation of nickel and cobalt derivatives of organic thioacids. In the reaction between nickel(II) dithiobenzoate and carbon monoxide in the presence of HS ion we assumed the formation of a sulfur-bridged nickel(IV) complex (VII, 32). More recent investigations (84), however, have shown that half the nickel appears as a monomeric nickel(II) complex of the same empirical formulation, formed by insertion of a sulfur atom in the dithio ligand, the other half of the nickel being reduced to nickel(O) by the sulfide. 

The macrocyclic thiaether-esters 84, 85, and 86 were prepared by the reaction of 2,2 -dithiobenzoic acid dichloride with corresponding diols in 31%, 80%, and 85% yields, respectively <2005PS1953>. The complexation abilities of these thiaether-esters toward Li+, Na+, K+, Mg2+, Ca2+, Sr2+, Ba2+, Co2+, and Ni2+ were measured by the solvent extraction experiments. The results showed that 84 exhibits stronger selectivity toward Li+, 85 toward Ba2+, and 86 toward K+. 

ZnnL2 and NinL2 complexes of the para-substituted dithiobenzoic acid (C (III2 OC6II4CS2 ) make unusual liquid crystals—metal mcsogcns, which are phases that act as self-contained, nonpolar support phases that substrates can diffuse into and out of. Ni"L2 s separate polyaromatic hydrocarbons (PAFfs) and phenols, whereas ZnnL2 s separate R2S and phenol substrates.50,51... 

The zinc(II) complexes of the dithiobenzoates were also of some interest as it appeared that different forms could be isolated, depending on whether crystallized or... 

Tetrathiafulvalenes can be prepared in a number of ways, for example via l,3-dithiole-2-thione-4,5-dithiolate - the simple salts of this dianion are not very stable, but can be stored as a zinc complex, or as the dithiobenzoate shown below. 

There have only been a few examples of cobalt and rhodium complexes bearing dithiocarboxylato ligands, such as the cobalt complex 41 which bears a bridging dithiobenzoate ligand, as shown in Fig. 11 [87-91], while there are a few (interesting) examples of iridium complexes. Treatment of a stable iridabenzene...
