The ability of [PtX₂(Me₂phen)] (Me₂phen = 2,9-dimethyl-1,10-phenanthroline, X = Cl, Br, I) to act as olefin scavengers, easily giving stable trigonal bipyramidal five-coordinated platinum species [PtX₂(Me₂phen)(η²-olefin)], has been checked toward [(C₅Me₄CH₂CH ₂CHCH₂)Ir(Me)(CO)(Ph)], a cyclopentadienyl complex containing an olefinic function introduced by ring methyl activation in the pentamethylcyclopentadienyl iridium(III) complex [(C₅Me ₅)Ir(Me)(CO)(Ph)]. The reaction of [PtI₂(Me ₂phen)] with [(C₅Me₄CH₂CH ₂CHCH₂)Ir(Me)(CO)(Ph)] results in the formation of the heterometallic binuclear complex [PtI₂(Me₂phen){(C ₅Me₄CH₂CH₂CHCH₂)Ir(Me) (CO)(Ph)}] which is stable and has been completely characterized by elemental analysis, ¹H, ¹³C, and ¹⁹⁵Pt NMR spectroscopy.
