卤化亚铜三苯基膦络合物(Ph_3P)_3Cu_nX_n(n=1,2;X=Cl,Br,I和CN)具有较好的催化活性和选择性,因而引起了人们的注意。X射线衍射研究表明(Ph_3P)_3CuX中Cu具有四配位的结构,而(Ph_3P)_3Cu_2X_2中Cu却具有四配位和三配位的结构。由XPS来表征它们的成键特征的工作尚未见诸报道。实验按文献[6]所述方法制备络合物。经熔点测定、元素分析,证实所制样品的纯度符合要求。按标准方法纯化氯化亚铜和溴化亚铜,并将新制样品置于充满高纯氮的干燥器中。测试
The cuprous halide triphenylphosphine complex (Ph_3P) _3Cu_nX_n (n = 1, 2; X = Cl, Br, I and CN) has attracted more attention due to its good catalytic activity and selectivity. X-ray diffraction studies show that Cu has a four-coordinated structure in (Ph_3P) _3CuX, whereas Cu in (Ph_3P) _3Cu_2X_2 has a four- and three-coordinate structure. The work of characterizing their bond formation by XPS has not been reported. The experiment was carried out according to the method described in [6] to prepare the complex. The melting point determination, elemental analysis confirmed that the purity of the sample prepared to meet the requirements. The cuprous chloride and cuprous bromide were purified according to standard methods and the fresh samples were placed in a desiccator filled with high purity nitrogen. test
