摘要：

The ternary sodium platinum hydride Na2PtH6 was prepared via the reaction of sodium hydride with platinum sponge at 770 K and 1500-1800 bar hydrogen pressure. Its structure was determined by X-ray investigations of powdered samples in the temperature range 295-9 K and a neutron diffraction experiment on the deuterated compound at room temperature. The atomic arrangement in Na2PtH6 is isotypic with that of K2PtCl6. These results show that platinum could be oxidized under high hydrogen pressure up to oxidation state 4+.
