The first examples of half-sandwich Rh(i) complexes stabilized by borane coordination have been prepared and structurally characterized. As substantiated by NMR spectroscopy and single-crystal X-ray diffraction, the phosphine-borane ligand iPrP-(o-CH)-BFxyl 1 [Fxyl = 3,5-(FC)CH] engages in tight η-BCC or η-B coordination, depending on the metal environment.
