The ternary hydride Na//2PdH//2 was synthesized by the reaction of sodium hydride with palladium in a hydrogen atmosphere at 370 degree C. The structure was derived from X-ray investigations on powdered samples and on a single crystal as well as from neutron diffraction experiments on the deuterated compound. Na//2PdH//2 crystallizes in the tetragonal space group I4/mmm and is isotypic with Na//2HgO//2. The atomic arrangement is characterized by a novel linear left bracket PdH//2 right bracket complex.
