The complexes [ Pt{(P(O)(OMe)₂)₂H}₂] and [ PtCl(PPh₃){(P(O)(OMe)₂) ₂H}] react with Tl(acac) in chloroform or with KOH in methanol solution to yield thetrinuclear and binuclear complexes, [ Pt{m -P)O)(OMe)₂}₄M₂] and [ PtCl(PPh₃){m -P(O)(OMe)₂ }₂M] (M = Tl, K), respectively. These derivatives react with (PtMe₃)₂SO_4· 4H₂O or [ {Me₃PtI}₄] with formation of the solvated complexes [ Pt{m -P(O))OMe)₂}₄{PtMe ₃(MeOH)}₂] and [ PtCl(PPh₃){m -P(O)(OMe)₂ }₂{PtMe₃(MeOH)}] .Addition of donor ligands displaces the coordinated methanol to afford the corresponding adducts [ Pt{m -P(O)(OMe)₂}₄{PtMe₃L}₂] (L = py, 3,5-Me₂py, P(p-MeOPh)₃}and [ PtCl(PPh₃){m -P(O)(OMe)₂ }₂{PtMe₃L}] (L = py, PPh₃). The complexes are characterized by elemental analysis, and IR and NMR spectroscopy
