Preparation and vibrational spectra of tetra-n-propylammonium carbonyldichloro-organoplatinate(II) salts, and a comparison of their carbon-13 and platinum-195 nuclear magnetic resonance properties with those of organomercury compounds

Abstract

Salts, [NPrⁿ₄][PtCl₂R (CO)](R = Me, Et, Prⁿ, Prⁱ, Buⁿ, or Ph), have been prepared from the reaction of [NPrⁿ4]_2-[Pt₂Cl₄(CO)₂] with HgR₂, but derivatives with R = Bu^t, C₂H₃, or C₃H₅ could not be obtained. Infrared and Raman spectra are reported and discussed. The ¹H, ¹³C, and ¹H-{¹⁹⁵Pt} INDOR spectra have been investigated. The behaviours of ¹J(PtC) and δ(¹⁹⁵Pt) are discussed with reference to the ¹³C parameters and δ(¹⁹⁹Hg) of the mercury compounds, [HgX(R)](X = Cl, Br, I, or R).
