Cationic and Neutral Heterometallic Ir-Group 12 Element Polyhydride Compounds: Synthesis, Structure and Reactivity.

ABSTRACT: The preparation and reactivity of some Ir-Zn and Ir-Cd heterometallic hydride complexes are described. Treatment of [Ir(IPr)₂H₂][BAr^F₄] (1; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene; Ar^F = 3,5-C₆H₃(CF₃)₂) with M'R₂ (M' = Zn; R = Ph, Me, Et; M' = Cd, R = Me) and Me₃SiCH=CH₂ results in dehydrogenation of an IPr isopropyl substituent, along with R-H elimination, to form square-pyramidal [Ir(IPr)(IPr″)(M'R)H][BAr^F₄] (M'R = ZnPh (4a); ZnMe (4b); ZnEt (4c); CdMe (8); IPr″ = dehydrogenated IPr) featuring apical M'R ligands.
