A Structurally Characterized Cobalt(I) σ-Alkane Complex.

ABSTRACT: A cobalt σ-alkane complex, [Co(Cy₂ P(CH₂ )₄ PCy₂ )(norbornane)][BAr^F ₄ ], was synthesized by a single-crystal to single-crystal solid/gas hydrogenation from a norbornadiene precursor, and its structure was determined by X-ray crystallography. Magnetic data show this complex to be a triplet. Periodic DFT and electronic structure analyses revealed weak C-H→Co σ-interactions, augmented by dispersive stabilization between the alkane ligand and the anion microenvironment. The calculations are most consistent with a η¹ :η¹ -alkane binding mode.
