“…Overall, the bonding parameters of the two complexes such as the X-Pt-X angles and the Pt-X and PtMe bond lengths are very similar to related [(COD)Pt(Me)] complexes [43][44][45][46][47]49,50,52,[90][91][92]. The same is true of the Pt-S bonds when compared with similar complexes [50,52,79,91]. A closer look reveals that the Pt-S bond is shorter for the DMSO ligand [91], respectively, are slightly longer than is found for the DMSO complex, although the NMR data suggest stronger Pt-S binding in these neutral complexes.…”

“…2 We have been interested in platinun monometallic and heterobimetallic complexes contaning thiolate ligands, and have recently obtained the complexes shown in Figure 1. 4 Pt (IV) complexes related to 1 and 2 were reported to undergo reductive elimination of SnClR 3 to originate the corresponding Pt(II) compounds. 3,5 If 1 and 2 presented the same type of behavior, they would be usefull starting materials for the type of complex we were planning to prepare, especially from complex 1, upon reaction with dppen (dppen = Ph 2 PCH=CHPPh 2 ), as represented (Scheme1).…”

O complexo de Pt(II) [Pt(SPh) 2 (dppen)] (4) , (dppen, Ph 2 PCH=CHPPh 2 ), estável, foi obtido de [PtCl(SPh) 2 (SnPh 3 )cod] (1) (cod = 1,5-ciclooctadieno), por eliminação redutiva de SnClPh 3 e substituição do ligante cod pela difosfina, porém em baixo rendimento. Contudo, quando [Pt(SPh) 2 cod] (3) foi utilizado como material de partida, 4 foi obtido em rendimento de 80%. A viabilidade dessas reações foi sugerida por estudos de TG dos materiais de partida. O complexo 4 foi caracterizado por espectroscopia de RMN multinuclear ( 195 Pt, 31 P, 1 H e 13 C), IV e análise elementar. A estrutura molecular de 4, resolvida por um estudo de difração de raios X, exibe geometria quadrática plana ligeiramente distorcida e distâncias de ligação C=C e Pt-P pequenas, o que foi interpretado em termos de uma interação π entre a ligação dupla e a ligação metal-ligante, de acordo com dados descritos na literatura.The stable Pt(II) complex [Pt(SPh) 2 (dppen) (4), (dppen, Ph 2 PCH=CHPPh 2 ) was obtained from [PtCl(SPh) 2 (SnPh 3 )cod] (1) (cod = 1,5-cyclooctadiene) by reductive elimination reaction of SnClPh 3 and substitution of the cod ligand by the diphosphine, albeit in low yields. Yields of 80% were obtained when [Pt(SPh) 2 cod] (3) was used as the starting material instead. The viability of these reactions was suggested by a TG study, performed on the starting materials. Complex 4 was characterized by multinuclear NMR ( 195 Pt, 31 P, 1 H and 13 C) and IR spectroscopies and elemental analysis. The molecular structure, solved by an X-ray diffraction study, exhibted a slightly distorted square-planar geometry and short C=C and Pt-P bond distances which were interpreted in terms of a π interaction between the double bond and the metal-ligand bond, as observed for other diphosphine compounds described previously.

There has been considerable interest in the study of organic ligands containing two or more different donor atoms because such ligands through light on the nature of the metalligands bonding. Selenium and bismuth metals react with di-2-pyridyldisulfide (Py2S2) in refluxing toluene to give the compounds Se(pyS)4 and Bi(pyS)3 in high yield. Reactions of selenium or bismuth/Py2S2 and iodine in different molar ratio was carried out in refluxing toluene led to the formation of Se(pyS)3I, Se(pyS)2I2, Bi(pyS)2I and Bi(pyS) I2 respectively. All the compounds were characterized physico-chemically and their antibacterial activity were studied 1,2. Copper and nickel powder react directly with sodium dithiocarbamate in organic solvents and produce the corresponding metal complexes. The result showed that the copper powder react in chloroform more readily than any other system examined. This reaction has been successfully applied in the determination of copper content in brass and bronze powder 3. The powder of tin metal is oxidized by Et2P(S)SS(S)PEt2 to tin(II) diethyldithiophosphate, the reaction involve the insertion of the metal into the S-S bond 4 .
