Formation of a σ-alkane Complex and a Molecular Rearrangement in the Solid-State: [Rh(Cyp2PCH2CH2PCyp2)(η2:η2-C7H12)][BAr4F]

Addition of H-2 to the precursor [Rh(Cyp(2)PCH(2)CH(2)PCyp(2))(eta(2):eta(2)-C7H8)][BAr4F] gives the sigma-alkane complex [Rh(Cyp(2)PCH(2)CH(2)PCyp(2))(eta(2):eta(2)-C7H12)][BAr4F] by a single-crystal to single-crystal reaction, as characterized by X-ray crystallography, SSNMR spectroscopy, and periodic DFT. An unexpected rearrangement of the {Rh(L-2)}(+) fragment is revealed.
