Formation of a σ‑alkane Complex and a Molecular Rearrangement in the Solid-State: [Rh(Cyp2PCH2CH2PCyp2)(η22‑C7H12)][BArF4]

Addition of H2 to the precursor [Rh­(Cyp2PCH2­CH2PCyp2)­(η22-C7H8)]­[BArF4] gives the σ-alkane complex [Rh­(Cyp2PCH2­CH2PCyp2)­(η22-C7H12)]­[BArF4] 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(L2)}+ fragment is revealed.
