Iridium(III) hydrides derived from an iridium(I) substrate by oxidative addition and cyclometallation of germanium(II) bis(trimethylsilyl)amide; X-ray structures of [{CH2Me2SiN(R)(NR2)Ge}HIr(µ-Cl)2{Ge(NR2)N(R)SiMe2CH2}IrH{Ge(NR2)2}] and [lr{GeCl(NR2)N(R)SiMe2CH2}(CO)2H{Ge(NR2)2}](R = SiMe3)

Abstract

Treatment of [{Ir(η-C₈H₁₄)₂(µ-Cl)}₂] with Ge(NR₂)₂ in n-C₆H₁₄ at 20 °C (C₈H₁₄= cyclo-octene, R = SiMe₃) in the absence or presence of CO leads to [{[graphic ommitted]H{Ge(NR₂)₂}](1) or [[graphic ommitted](CO)₂H{Ge(NR₂)₂}](2), respectively; the Ir–Ge distances in (1) and (2) range from 2.325(3) to 2.470(3)Å.
