Abstract

Abstract: The straightforward synthesis of the cationic, purely organometallic Ni I salt [Ni(cod)2 ] + [Al(OR F )4 ] − was realized through a reaction between [Ni(cod)2 ] and Ag[Al(OR F )4 ] (cod=1, 5‐cyclooctadiene). Crystal‐structure analysis and EPR, XANES, and cyclic voltammetry studies confirmed the presence of a homoleptic Ni I olefin complex. Weak interactions between the metal center, the ligands, and the anion provide a good starting material for further cationic Ni I complexes. Abstract : Homoleptic nickel(I) complex : A solvent‐free organometallic nickel(I) complex was easily obtained from the reaction between [Ni 0 (cod)2 ] and Ag[Al(OR F )4 ] (cod=1, 5‐cyclooctadiene, OR F =OC(CF3 )3 ). Crystal‐structure analysis, EPR spectroscopy, XANES, and cyclic voltammetry confirmed the salt to be [Ni(cod)2 ] + [Al(OR F )4 ] −, a good starting material for the synthesis of other cationic Ni I complexes.
