Abstract

Thermally stable mono-tri-t-butylphosphine adducts of alane and gallane, H₃Mp^tBu₃ (M Al, 1; M Ga, 2) and the gallane rich adducts of 1,2-bis(diisopropylphosphino)ethane and 1,2-bis(diphenylphosphino)ethane, [(H₃Ga)₂{(PR₂CH₂)₂}] (R ⁱPr, 3; R Ph, 4), have been prepared from LiMH₄/HCI/phosphine; reactions involving H₃MNMe₃/P^tBu₃ also yield 1 and 2, for the former via a mixed donor ^tBu₃PAl(H)₃NMe₃ (5), which decomposes to 1 and NMe₃ at ca. 40°C; compounds 1 and 2, and the previously reported alane analogue of 3, viz. [(H₃Al)₂{(PⁱPr₂CH₂)₂}] (6) have been shown to be four coordinate (Al-P, 2.471(3) and 2.451(3) Å, 1 and 6; Ga-P 2.444(6) Å 2). Ab initio calculations on relevant model systems, H₃GaPMe₃ (DZP level) and H₃Al(PR₃)₂ (R H or Me; D95* level) are reported, Ga-P 2.550 Å, and Al-P 2.828 Å (R H), 2.786 Å (R Me).
