Proton and fluorine spin-lattice relaxation times as well as second moments were measured in guanidinium hexafluorogallate over a wide range of temperature. The analysis of all cross-relaxation effects occurring in the four unlike spin system revealed two cation motions and yielded their activation parameters. It was found that the anion size did not influence C_{3} reorientation of cation nor isotropic reorientation of anion.
