摘要：
The ternary sodium palladium hydride Na2PdH4 and its analogous deuteride were prepared via the reaction of sodium hydride (deuteride) with palladium sponge at 770 K and 1800 bar hydrogen (deuterium) pressure. Its structure was determined from X-ray diffraction studies of powder samples in the temperature range 9 to 600 K and an elastic neutron diffraction experiment on the deuterium compound at room temperature. The atomic arrangement in Na2PdH4 contains isolated square-planar [PdH4](2-) groups and is isotypic with that of Na2PtH4 (space group 14/minin, Z = 2).
