Three novel examples of KrâN bonds derived from perfluoroalkylnitriles, the RFCNâKrF+ cations, and their xenon analogues RFCNâXeF+(RF= CF3, C2F5, n-C3F7), have been prepared and characterized in BrF5 solvent by 19F and 129Xe n.m.r. spectroscopy; the XeâN bonded cation s-C3F3N2NâXeF+, synthesized as the AsF6â salt, is stable at room temperature and has been fully characterized by 129Xe and 19F n.m.r. and Raman spectroscopy.
三种新型的Kr–N键结合物,由全氟烷基腈、RFCN–KrF+阳离子及其氙类似物RFCN–XeF+(RF = CF3, C2F5, n-C3F7)所构成,已在BrF5溶剂中通过19F和129Xe核磁共振光谱进行了制备和表征。与氙结合的阳离子s-C3F3N2N–XeF+以AsF6–盐的形式合成,在室温下稳定,并已通过129Xe和19F核磁共振及拉曼光谱进行了充分表征。
