Abstract: | The crystal and molecular structures of the title compound, 3‐bromo‐3‐(dibenzylphenylphosphonio)‐2,2‐diphenyl‐5‐trifluoromethyl‐1H‐benzoe]1,2]phosphanickelepine, NiBr(C22H17F3P)(C20H19P)], which was obtained as the major regioisomer from insertion of HCCCF3 into the Ni—C bond of the five‐membered phosphanickelacycle NiBr(o‐C6H4CH2PPh2‐κ2C,P){PPh(CH2Ph)2}], have been determined. Principal geometric data include the Ni—X bond lengths Ni—Br 2.3343 (4) Å, Ni—P 2.1867 (7) and 2.2094 (7) Å, and Ni—C 1.882 (3) Å, and the two trans angles P—Ni—P 171.55 (3)° and Br—Ni—C 176.88 (9)°. |
