摘要
The composition and structure of cyclic sulfoxide derivative Pd(II) complex were investigated. The coordinated number was studied with slope method. The coordination number is 2 in lower acidity, but it is 3 in higher acidity. Four methods, UV (ultraviolet) spectra, FTIR (Fourier transform infrared) spectra, H-1-NMR (nuclear magnetic resonance) spectra, and C-13-NMR spectra, were used to determine the coordinated atom in complex. Pd is coordinated with O and S atom in S=O group in lower acidity media. The conversion of coordination bond appears with an increasing time. Pd is coordinated with S atom in S=O group in higher acidity media, and inter-ligand-transfer reaction occurs.
