A heterobimetallic complex with a CF2 bridge, [CpFeIr(CO)2(PMe2Ph)2(μ-CO)(μ-CF 2)][BF4] (1a), was prepared by the oxidative addition of [CpFe(CO)2(CF2)]+ to Ir(Cl)(CO)(PMe2Ph)2. The [BPh4]- salt of the dimetal compound 1a undergoes a Lewis acid displacement with BCl3 to generate the BCl3 adduct of Ir(Cl)(CO)(PMe2Ph)2 and [CpFe(CO)2(CF2)][BPh4]. The crystal structure of 1a reveals a nearly symmetric CF2 bridge between Fe and Ir, whereas a CO ligand is in a semibridging position between these two metal atoms. Crystal data: monoclinic, space group P21/n, a = 9.308 (2) A?, b = 16.447 (3) A?, c = 20.997 (4) A?, β = 98.69 (2)°; Z = 4; 388 parameters were refined on 4901 reflections with I > 3σ(I) to yield R = 0.036 and Rw = 0.049.
