【Abstract】 Objective: To investigate the synthesis and spectral properties of hydroxy benzophenone complexes.Methods: A new cobalt(Ⅲ) complex M(MBP) was synthesized in ethanolic-water system by using 2-hydroxy-4-methoxybenzophenone and cobalt chloride,which were characterized by element analysis and laser-desorption ionization time-of-flight mass spectrometry(LDI-TOF-MS) and were also studied by the fourier transform infrared characteristic spectra(FTIR).Results:HMBP ligand formed a 3:1 complex through the carbonyl oxygen atoms and hydroxyl oxygen atoms and the central metal.There were significant changes of intrinsic absorption of the ligand compared with IR characteristic absorption spectra of the complex.The IR characteristic absorption peak positions of M─O bond were also confirmed.Conclusion:Stable complexes were obtained.更多还原
