The prepn. of new hydrido cationic species of the general formula [Pt(PEt3)2LH]X is reported (L = AsPh3, SbPh3, thiourea, sopropylamine, 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. Equil. indexes for the reactions trans-[Pt[PEt3)2HCl] + L .rdblhar. trans-[Pt(PEt3)2LH]+ + Cl- in EtOH (L = PPh3, AsPh3, SbPh3, pyridine, 4-cyanopyridine, isopropylamine, and thiourea) have also been measured. The greater the equil. index of the cationic hydrido species the lower is the stretching frequency of the Pt-H bond.

Abstract
The prepn. of new hydrido cationic species of the general formula [Pt(PEt3)2LH]X is reported (L = AsPh3, SbPh3, thiourea, sopropylamine, 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. Equil. indexes for the reactions trans-[Pt[PEt3)2HCl] + L .rdblhar. trans-[Pt(PEt3)2LH]+ + Cl- in EtOH (L = PPh3, AsPh3, SbPh3, pyridine, 4-cyanopyridine, isopropylamine, and thiourea) have also been measured. The greater the equil. index of the cationic hydrido species the lower is the stretching frequency of the Pt-H bond.
