Interaction of potassium hexahalogenoosmates(IV) with DMSO

Full Text:

Abstract

Interaction of К2 [OsX6], where X=Cl, Br ( СOs = n · 10-4 – n · 10-2 mol/l) with DMSO has been studied by electronic absorption spectroscopy at room temperature and heating. It was established that interaction was accompanied by replacement of halide-ions in [OsX6]2- with DMSO molecules and reduction of osmium(IV) to osmium(III), and then to osmium(II). The intermediate forms were defined: [OsIV(dmso-O)Br5] and [OsIII(dmso-S)2Br4]. The final product of the interaction in solution in case of heating was cis,fac-[OsII(dmso-S)3(dmso-O)X2], which slowly isomerizes to trans-[OsII(dmso-S)4 Х2 ] at room temperature .
