Abstract
Presented herein is a solid-state 71Ga and 69Ga NMR study of several six-coordinate gallium-oxygen compounds: Ga(acac)3, Ga(thd)3, Ga(trop)3, and (NH4)3[Ga(cit)2]·4H2O. Spectra of stationary and magic angle spinning (MAS) samples are reported, and their electric field gradient (EFG) and chemical shift anisotropy (CSA) tensor parameters are determined at the 71Ga and 69Ga sites. Experimental results are complemented with density functional theory (DFT) calculations using CASTEP. Tensor parameters are compared with those of similar compounds containing other group-13 metals including 27Al and 115In, and periodic trends are considered. This work shows that solid-state NMR studies of gallium compounds are worthwhile and practical with modern techniques, as 71Ga and 69Ga NMR spectra of the chosen compounds were successfully acquired and interpreted. The potential for further studies is discussed.
