  The complexation behaviour of the bidentate ligand tetrakis(O-isopropyl)methylenediphosphonate (L = (iPrO)(2)P(O)CH2-P(O)(OiPr)(2)) with lanthanide ions has been studied by using triflates Ln(OTf)(3) (Ln = La, Pr, Nd) as sources of the Ln(3+) cations. At the 2:1 L:Ln stoichiometric ratio, adducts of composition [Ln(OTf)(3)(L)(2)(OH2)(2)] were isolated (Ln = La, Pr, Nd). In the X-ray structure of the cationic [Nd(OTf)(2)(L)(2)(OH2)(2)](OTf), the two coordinated triflates are monodentate. Finally, at higher L/Ln ratios, complexes were difficult to isolate because of a high degree of solvation, but, in one instance, with Ln = La, by using inert atmosphere techniques, the tripositive complex. [La(L)(4)](OTf)(3)(CH3CN)(3) has been obtained and characterised by X-ray. By contrast, in the crystal structures of [Ln(NO3)(3)(L)(2)](CH3CN)(2), (Ln = Ce, Pr, Nd), all three nitrates are bidentate.
