[Ni(cod)2][Al(OR(F))4], a Source for Naked Nickel(I) Chemistry

Angew Chem Int Ed Engl. 2015 Dec 1;54(49):14706-9. doi: 10.1002/anie.201506475. Epub 2015 Oct 13.

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.

Keywords: crystallography; cyclic voltammetry; density functional calculations; electron paramagnetic resonance; nickel(I) complexes.
