Ea. Piocos et Bs. Ault, MATRIX-ISOLATION INVESTIGATION OF THE REACTION-PRODUCTS OF TRIMETHYLGALLIUM WITH CH3OH, CH3SH AND H2S, Journal of molecular structure, 317(3), 1994, pp. 223-232
The 1:1 molecular adducts of trimethylgallium with methanol, methaneth
iol and hydrogen sulfide were isolated and characterized for the first
time using the matrix isolation technique with FT-IR detection. Spect
ral analysis showed these adducts to be less strongly bound than the c
omplexes of (CH3)(3)Ga with the group VI dimethyl compounds (e.g. (CH3
)(2)O). Evidence was obtained for loss of the C-3 symmetry axis in the
complex, as well as for a distortion from planarity of the GaC3 skele
ton. Spectral shifts upon complex formation for these complexes, and t
hose studied previously, correlate well with the proton affinity of th
e base subunit in the complex.
