An orientational disorder of the cation in [(PyO)D][AuCl4] crystal was investigated by the 35Cl NQR and 1H NMR measurements. A structural phase transition was found at ca. 70 K from the temperature dependence of the NQR frequencies both in [(PyO)D][AuCl4] and [(PyO)H][AuCl4]. Temperature dependence of the spin-lattice relaxation time T1 of the NQR of [AuCl4]− could be interpreted by an electric field gradient modulation due to the motion of the cation. Characteristics of T1 of 35Cl NQR as well as that of 1H NMR suggest a dynamic orientational disorder of the cation. [ABSTRACT FROM AUTHOR] |
