Infrared studies and equilibria of new platinum(II) hydrido-complexes

Abstract

The preparation of new hydrido-cationic species of the general formula [Pt(PEt3)2LH]X is reported (L = As Ph3 SbPh3, thiourea, isopropylamine, 3-chloropyridine, 3-methylpyridine, 2,6-dimethylpyridine, and 4-cyanopyridine), together with the reaction of trans-[Pt(PEt3)2(H)Cl] with 1,2-diarsinoethane. Equilibrium indices for the reactions trans-[Pt(PEt3)2HCl]+ L [leftrightharpoons]trans-[Pt(PEt3)2LH]++ Cl in ethanol (L = PPh3, AsPh3, SbPh3, pyridine, 4-cyanopyridine, isopropylamine, and thiourea) have been also measured. The greater the equilibrium index of the cationic hydrido-species the lower is the stretching frequency of the Pt–H bond.
