Group 10 Element Compounds Ni, Pd, Pt

It is well-known that the reaction of palladium(II) acetate with an excess of thiobenzoic acid in benzene gives the polymeric thiobenzoato palladium complex 51 [Pd(PhCOS)2]x (x 3) [83], although the complex formed from the reaction of PdCl2 with sodium thiobenzoate in water was reported to be dimeric [Pd(PhCOS)2]2 in benzene [253]. The thiobenzoato complexes 51 obtained by the reaction of Na2PdCl4 with sodium thiobenzoate react with Lewis bases to give the neutral monomeric complexes trans-Pd(PhCOS)2(L)2 (L R P, R3AS, RsSb, pyridines, and so on), where the PhCOS ligands are monodentate 

Similar to the palladium complexes mentioned above, the complex Pt(PhCOS)2]x (55), obtained by the reaction of Na2PtCl4 with sodium thiobenzoate, also reacts with Lewis bases such as phosphines and pyridines giving the neutral mono-
