Abstract

Reaction of 2 equivalents of LiGaH4 or 1 equivalent of NaGaH4 with [ZnCl2(pmdeta)] (pmdeta = N,N,N′, N″,N″-pentamethyldiethylenetriamine) in diethyl ether at 0 °C gives the heterobimetallic species, [Zn(η1-GaH4) Cl (pmdeta)] 1, whereas reaction of [M′GaH4] with [ZnCl 2(tmen)] (tmen = N,N,N′,N′-tetramethylenediamine) in 2 : 1 (M′ = Li) or 1 : 1 (M′ = Na)·molar ratio, gives [Zn(η2-GaH4) Cl (tmen)] 2; the analogous [Zn(η2-BH4)(Cl(tmen)] 3 is prepared from reaction with 2 molar equivalents of LiBH4 or with 1 equivalent of NaBH 4; complexes 1 and 3 are structurally characterised, the former represents the first reported structure of the GaH4 moiety.
