Reactions of Ir(I)-triflate complexes trans-Ir(OTf) (CO) (PR3)2 (PR3 = PPh3, 1; PR3 = PMePh2, 2) with Pt0-π-ethylene complexes Pt(H2C=CH2)(PR′3)2 (PR′3 = PPh3, 3; (PR′3)2 = Ph2P(CH2)3PPh2, 4) in CH3NO2 result in C-H bond activation and the ready formation of the novel heterobimetallic Ir-Pt complexes [(PR3)2(CO)Ir(μ-H)(μ-η2:η 1-CH=CH2)Pt(PR′3)2] +[OTf]- (PR3 = PR′3 = PPh3, 5; PR3 = PMePh2, PR′3 = PPh3, 6; PR3 = PPh3, (PR′3)2 = Ph2P(CH2)3PPh2, 7; PR3 = PMePh2, (PR′3)2 = Ph2P(CH2)3PPh2, 8). A definitive structural determination for these heterobimetallic Ir-Pt complexes has been established by an X-ray diffraction study on complex 5 (triclinic, P1 (No. 2), a = 13.321 (1) A?, b = 15.461 (2) A′, c = 17.753 (2) A?, α= 90.37 (1)°, β = 95.47 (1)°, γ = 100.92 (1)°, Z = 2). Reactivity tests with one of the heterobimetallic complexes 7, using Ph2P(CH2)3PPh2 and acids, have also been conducted.
