Complexes of hydrophilic triphenylphosphines modified with gem-bis(phosphonate) moiety. An unusual simultaneous cis and trans arrangements in the Pt(II) dinuclear complex
Bis(phosphonic acid) derivative of triphenylphosphine was synthesized. Mono- and dinuclear complexes with palladium(II), platinum(II) and rhodium(I) were investigated in solution and the solid state.
