IR and Raman study of Pt(II) and Pd(II) complexes of amino substituted phosphine oxides: Normal coordinate analysis

Abstract

IR and Raman spectra of Pt(dapo) 2Cl 2 and Pd(dapo) 2Cl 2 (dapo=dimethyl(aminomethyl)phosphine oxide) have been measured in the 200–4000 cm −1 frequency range. Both the IR and Raman spectra show that dimethyl(aminomethyl)phosphine oxide ligands are monodentate coordinate. The results from the normal coordinate analysis calculations confirm the monodentate coordination of the ligands in agreement with some literature data. For Pd(dapo) 2Cl 2 complex the possibility for bidentate coordination of one dapo ligand is also considered.
