Abstract
The synthesis of [t-Bu(H)Ga(μ-NEt2)]2 (1) was accomplished by the addition of 4 t-BuLi to [Cl2Ga(μ-NEt2)]2. Evidence suggests that two tert-butyl groups are lost as isobutylene and result in Ga−H bond formation. The gallium hydride 1 is remarkably stable toward ambient air, oxygen, photolysis, and moderate heating; however, in CHCl3 the hydride is replaced by chloride, producing [t-Bu(Cl)Ga(μ-NEt2)]2 (2). Compound 1 may also be synthesized by sequential tert-butyl additions to [Cl2Ga(μ-NEt2)]2. A singly substituted tert-butyl dimer, t-Bu(Cl)Ga(μ-NEt2)2GaCl2 (3), was also isolated, and interconversions between 1, 2, and 3 are described. Compound 1 was tested for utility in the chemical vapor deposition of GaN and produced gallium-rich films at low temperatures (<250 °C) with limited nitrogen incorporation due to facile Et2NH elimination.
