The complex cis-Pt(Ph3Ge)2(PMe2Ph)2 underwent smooth isomerization to give the trans-isomer at room temperature via an associative five-coordinated intermediate. Thermodynamic parameters and activation energy for the cis to trans isomerization were obtained, ΔH# = 105 kJ mol-1, ΔS# = 12.5 J mol-1 K-1, and Ea = 107 kJ mol-1, respectively. Heating of trans-Pt(Ph3Ge)2(PMe2Ph)2 at 50 °C for 36 days produced trans-PtPh(Ph3Ge)(PMe2Ph)2 followed by the formation of trans-PtPh2(PMe2Ph)2, Pt(PMe2Ph)4, and Ph4Ge finally via elimination of the phenyl group from Ph3Ge ligand with liberation of the Ph2Ge unit and subsequent reductive elimination of the remaining Ph3Ge ligand at 80 °C for 1 month.

The complexes trans-[PtPh(OTf)(PMe2Ph)2] (1) and trans-[PtPh(OTf)(PPh3)2] (4) were synthesized from the corresponding chloro complexes in moderate yields. Complex 1 is slowly hydrolyzed in solution, giving the d
