摘 要：<正>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, 1H-NMR （nuclear magnetic resonance） spectra, and 13C-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.
