[Bis(dimethylsulphoxide) protium][trans-bisdimethylsulphoxidetetrachloroiridate(III)]

1988

Abstract [(DMSO)2H]trans-[IrCl4(DMSO)2] (DMSO = dimethylsulphoxide) has been structurally characterized. The hydrogen bonded cation [DMSOHDMSO]+ has a very short OHO bond distance (2.405 A) which compares well with that in the known rhodium analogue. The two DMSO ligands are trans on iridium and coordinate via the sulphur atoms. Earlier work had assigned the cis structure to the anion in this compound.

Sulphides of the platinum group elements—12. Bis(tetraphenylphosphonium) pentakaidekakissulphido platinates(IV)

Abstract Synthetic routes to tetraphenylphosphonium salts of [PtSx]2− are outlined, where x = 15 or 18. Generally, (PPh4)2[Pt(S5)3] is formed most readily. The compound [(C6H5)4P]2[PtS15], always solvated, has been obtained by synthesis in acetonitrile (sulphur, triethylamine, H2S and [PPh4]2[PtCl6]) and by metathesis (in DMF) from the known hydrated ammonium compound (NH4)2[Pt(S5)3]2H2O+2[Ph4P]Br→(Ph4P)2[Pt(S5)3]· DMF+2NH4Br, and from the dismutation (in acetone) 3PtS172−→PtS152−+2PtS182−. X-ray diffraction shows that crystals obtained from DMF and acetone are the solvated salts [Ph4P]2· [Pt(S5)3]· S, with solvent molecules (S) uncoordinated. In both, the three platinopentathian rings rela…
