Halide abstraction from [(Ph 3 P) 2 Rh(μ‐Cl)] 2 by the sodium salt of the weakly coordinating [BAr f 4 ] − anion [Ar f = C 6 H 3 (CF 3 ) 2 ‐3,5] in the presence of excess arene offers a convenient, high‐yielding route to the half‐sandwich cations [(arene)Rh(PPh 3 ) 2 ] + [BAr f 4 ] − [arene = benzene ( 1 ), toluene ( 2 )]. Crystalline samples of 1 and 2 are isomorphous [ a = 13.1270(2), b = 15.3030(2), c = 17.5760(3) Å, α = 74.620(1), β = 81.533(1), γ = 88.540(1)° for 1 ] and feature the arene ligand bound to the rhodium atom in η 6 fashion.
