Abstract

Proton magnetic resonance second moment and spin-lattice relaxation time were carried out on polycrystalline tris (n-propylammonium) enneachlorodiantimonate (III), (n-C₃H₇NH₃)₃Sb₂Cl ₉, in the temperature range of 10-370 K. The second moment measurements show that the structure is not rigid on the NMR scale at 10 K, the lowest temperature studied, and that CH₃ and NH₃ groups execute rotations about C₃ axis. The proton spin-lattice relaxation measurements reveal two minima due to the motions of the amino and methyl groups. Analysis of the relaxation data yields the activation energy barriers of 11.0 kJ mol^-1 and 5.8 kJ mol^-1, respectively, for the NH₃ and CH₃ groups' motion. NMR data confirm the phase transition at T_c = 232 K, known from different studies. © 1997 Elsevier Science B.V.
