A Structurally Characterized Cobalt(I) σ‐Alkane Complex

A cobalt σ‐alkane complex, [Co(Cy(2)P(CH(2))(4)PCy(2))(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. P...

Descripción
Sumario:A cobalt σ‐alkane complex, [Co(Cy(2)P(CH(2))(4)PCy(2))(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 η(1):η(1)‐alkane binding mode.
