N2 - The temperature dependences of the 1H spin-lattice relaxation time (T1) and the second moment (M2) of 1H NMR absorptions were measured for anhydrous tert-butylammonium hexachloro-stannate(IV) and its partially deuterated analogs [(CD3)3CNH3]2SnCl6 and [(CH3)3CND3]2SnCl6. Three kinds of cationic motions were revealed: the reorientations of the CH3 group about their C-C bonds, the NH3 group about its C-N bond, and the tert-butyl group about the C-N bond. Their motional parameters were determined. Among the three motions, the NH3 motion occurs at the lowest temperature with quite a small activation energy (9.9–10.0 kJ mol−1).
