Interaction between [(η⁶-p-cym)M(H₂O)₃]²⁺ (M^II = Ru, Os) or [(η⁵-Cp*)M(H₂O)₃]²⁺ (M^III = Rh, Ir) and Phosphonate Derivatives of Iminodiacetic Acid: A Solution Equilibrium and DFT Study.

ABSTRACT: The pH-dependent binding strengths and modes of the organometallic [(η⁶-p-cym)M(H₂O)₃]²⁺ (M^II = Ru, Os; p-cym = 1-methyl-4-isopropylbenzene) or [(η⁵-Cp*)M(H₂O)₃]²⁺ (M^III = Rh, Ir; Cp* = pentamethylcyclopentadienyl anion) cations towards iminodiacetic acid (H₂Ida) and its biorelevant mono- and diphosphonate derivatives N-(phosphonomethyl)-glycine (H₃IdaP) and iminodi(methylphosphonic acid) (H₄Ida2P) was studied in an aqueous solution. The results showed that all three of the ligands form 1:1 complexes via the tridentate (O,N,O) donor set, for which the binding mode was further corroborated by the DFT method. Although with IdaP^3-
