Syntheses and Spectroscopic properties of Palladium(Ⅱ) Complexes with Bidentate Aminophosphine of N,N-Dialkyl-N'-diphenylphosphinodiaminoethane
Myung-Ki Doh*, Bong-Gon Kim
Several new palladium(Ⅱ) complexes of aminophosphines, (Pd(L)X2), (L = Ph2PNH ++ NR2; R = CH3(L1), C2H5(L2) : X = Cl, Br, I, and NCS) that contain two different donor atoms of nitrogen and phosphorus as π-electron acceptor, were synthesized and characterized by conductivity measurement, ir, and UV/Vis-spectra. For the dithiocyanatopalladium(Ⅱ) complexes with aminophosphines, it was confirmed that the thiocyanate group trans to phosphorus is coordinated as Pd-NCS mode and the one trans to nitrogen as Pd-SCN mode, and the aminophosphines form six-membered chelate ring. The spectra of dihalogenopalladium(Ⅱ) complexes with aminophosphines show that the band maxima are shifted to the short wavelengths as the concentration is decreased.
