Palladium(II) coordination chemistry of monoethyl 2-quinolylmethylphosphonate

The synthesis and some spectroscopic properties of the new palladium(II) complexes with monoethyl 2-quinolylmethylphosphonate (2-mqmp) have been reported. It was shown that the molecular or the ionic complexes could be isolated depending on the acidity of the aqueous reaction solution. The square planar dihalide complexes with monodentate N-bonded ligand through the quinoline nitrogen were obtained at pH~3.5. Under acidic conditions at pH<3 the ion-pair salt complexes containing the protonated quinoline ligand as cation and the quinoliniummethylphosphonatetrihalopalladate complex as anion were isolated. These ionic complexes by heating in methanol were decomposed: the chloro complex to the molecular dichloropalladium adduct, while its bromo analogue gave a mixture of the dibromopalladium adduct and the ion-pair hexabromodipalladium salt complex. The chelate complex was isolated at pH > 6. In this compound 2-mqmp acts as a bidentate ligand through the quinoline nitrogen and the phosphonic acid oxygen. The new complexes were identified and characterized on the basis of elemental and thermogravimetric analysis, magnetic and conductance measurements as well as by infrared and positive/negative-ion FAB-mass spectroscopic studies.
