Amine adducts of tert-butylthiolate gallium hydrides - synthetic and X-raycrystallographic studies

Amine adducts of tert-butylthiolate gallium hydrides were synthesized for p ossible use as precursors to gallium sulfide films. Reactions of GaH3L (L = NMe3 or quinuclidine) with 1 or 2 equiv. of t-BuSH and GaH3-xClx (quin) wi th 1 or 2 equiv. of LiS-t-Bu produced mixtures of products. The complexes G aH(S-t-Bu)(2)(NMe3) and GaH2(S-t-Bu)(quin) were isolated as crystalline sol ids from the product mixtures and both were characterized by X-ray crystall ography. In the solid state, GaH(S-t-Bu)(2)(NMe3) is best described as havi ng a trigonal pyramidal geometry. The complexes Ga(S-t-Bu)(3)L (L = NMe3 or quinuclidine) were synthesized from GaH3L and a slight excess of t-BuSH. ( C) 2001 Elsevier Science Ltd. All rights reserved.
