| Abstract: | A cobalt σ‐alkane complex, Co(Cy2P(CH2)4PCy2)(norbornane)]BArF4], 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. |
