130 years after Mond discovered the first homoleptic carbonyl complex Ni(CO) , we report on a [Ni(CO) ] salt as the first synthesis of any homoleptic nickel carbonyl cation in the condensed phase. It was prepared by oxidation of nickel metal with the synergistic oxidant Ag[F{Al(OR ) } ]/0.5 I (R =C(CF ) ) in CO atmosphere. This D -symmetric metalloradical represents the last missing entry among the structurally characterized homoleptic carbonyl cations of Groups 6 to 11. Additionally, the nickel tricarbonyl-nitrosyl cation [Ni(CO) (NO)] was obtained by usage of NO[F{Al(OR ) } ] and all products were fully characterized by means of IR, Raman, NMR/EPR, single crystal and powder XRD.
在蒙德发现首个单核羰基配合物Ni(CO)₄的130年后，我们报道了一种[Ni(CO)₄]⁺盐，这是在凝聚相中首次合成的任何单核镍羰基阳离子。它是通过在CO气氛中用协同氧化剂Ag[F{Al(OR₂)₄}] / 0.5 I₂（R = C(CF₃)₃）氧化镍金属制备的。这种具有D₄h对称性的金属自由基代表了第6至11族结构表征的单核羰基阳离子中最后一个缺失的成员。此外，通过使用NO[F{Al(OR₂)₄}]获得了三羰基 - 亚硝酰镍阳离子[Ni(CO)₃(NO)]⁺，并且所有产物都通过红外光谱、拉曼光谱、核磁共振/电子顺磁共振、单晶和粉末X射线衍射进行了全面表征。
