摘　　要：PN^(P-)钳型镍硝酸根配合物2可通过其前体镍氯化物1与硝酸银复分解反应制备,产率高达95%;配合物2的结构通过核磁、红外、HRMS、X-射线单晶衍射等表征进行了确认,其中硝酸根以η^(1)-ONO_(2)的方式与金属镍配位。配合物2具有优异的光反应性质,通过控制光照时间,可分别转化为钳型镍硝基配合物3、氧原子分子内转移的硝基配合物4和配体磷完全氧化的镍双硝酸根配合物5。它们的结构均通过核磁和单晶表征证实,配合物3的结构还通过对比1与亚硝酸银反应生成产物的核磁数据进行了验证。A PN^(3)P-pincer nickel nitrate complex 2 was synthesized by metathesis of its precursor nickel chloride 1 and silver nitrate with a yield of 95%.NMR,IR,HRMS,and X-ray single-crystal diffraction characterizations confirmed the structure of complex 2,in which the nitrate is coordinated with nickel in the η^(1)-ONO_(2) manner.Complex 2 has excellent photoreactive properties and could be converted into nickel nitrite complex 3,nickel nitrite complex 4 with intramolecular oxygen atom transfer,and nickel dinitrate complex 5 with complete phosphorus oxidation by controlling the photolysis time,respectively.Their structures were all confirmed by NMR spectroscopy and single-crystal X-ray crystallography,and the structure of complex 3 was also verified by comparing the NMR spectra of product formed by the reaction of 1 with silver nitrite.
