The title compound, barium palladium oxide, Ba68Pd32Ox, x similar or equal
to 13.5 is a medium-sized cubic suboxide. Two of the four crystallographica
lly independent Ba atoms form a network of face-sharing octahedra with O at
oms occupying the central position of these octahedra, giving a network res
embling the pyrochlore structure. Two of three O-atom positions are fully o
ccupied and the third partially occupied. The remainder of the Ba atoms and
the Pd atoms are distributed in another network residing in the channels o
f the network of face-sharing O-Ba-6 octahedra.
