Abstract
Gallium-69 and -71 and
indium-115 n.m.r. spectra have been obtained for the tetrahalometallate anions
MX4- (M = Ga, In; X = Cl, Br, I) in dichloromethane
solution. For each element, mixtures of two halo anions gave mixed halo species
in the statistical distribution. For gallium, a mixture of the three halo
anions gave all 15 possible species in the statistical distribution. The effect
of the electric quadrupole moment is clearly reflected in the linewidths;
gallium-71 gave sharper lines and better resolution of the mixed species than
gallium-69 and the resonances for indium-1 15 were very broad.
