Pt(II) Complexes with Linear Diamines—Part I: Vibrational Study of Pt-Diaminopropane

A conformational analysis of the Pt(dap)Cl2 complex (dap=1,3-diaminopropane) was performed by vibrational spectroscopy (FTIR, Raman, and INS), coupled to quantum mechanical methods within the density functional theory (DFT) and effective core potential (ECP) approaches. A complete spectral assignment of the system was achieved, due to the combined use of all available vibrational spectroscopic techniques. A good agreement was found between experimental and theoretical results, as well as with reported data for analogous complexes (e.g., cisplatin).
