摘要：

The Cl-35 NQR frequencies, spin-lattice relaxation time and H-1 NMR relaxation time were measured on crystalline Na2PtCl6 . H2O at 77-350 K. The presence of three nonequivalent chlorine sites found by X-ray diffraction measurement is in agreement with the observed three NQR lines, which have different temperature dependences attributable to differences in the direction of H-bonding with water molecules. The three NQR lines correspond to three kinds of chlorines with different Pt-Cl distances and H-bond directions.
