A Series of Crystallographically Characterized Linear and Branched σ-Alkane Complexes of Rhodium: From Propane to 3-Methylpentane.

ABSTRACT: Using solid-state molecular organometallic (SMOM) techniques, in particular solid/gas single-crystal to single-crystal reactivity, a series of σ-alkane complexes of the general formula [Rh(Cy₂PCH₂CH₂PCy₂)(ηⁿ:η^m-alkane)][BAr^F₄] have been prepared (alkane = propane, 2-methylbutane, hexane, 3-methylpentane; Ar^F = 3,5-(CF₃)₂C₆H₃). These new complexes have been characterized using single crystal X-ray diffraction, solid-state NMR spectroscopy and DFT computational techniques and present a variety of Rh(I)···H-C binding motifs at the metal coordination site: 1,2-η²:η² (2-methylbutane), 1,3-η²:η² (p
