摘要：

The temperature dependences of the Cl-35 NQR frequencies and spin-lattice relaxation times in (ND4)(2)PtCl6 were measured from 4.2 to 400 K. The phase transition at 27.5 K induced by deuteration was confirmed to be a first-order one, although the transition was associated with rotary soft mo des like other deuterated ammonium hexachlorometallates. It was suggested from the NQR spectra observed in the low temperature phase that the low temperature structure is orthorhombic (Fmmm).
