Materials Data on PdO by Materials Project

PdO is Halite, Rock Salt structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pd2+ is bonded to six equivalent O2- atoms to form a mixture of corner and edge-sharing PdO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.27 Å) and two longer (2.29 Å) Pd–O bond lengths. O2- is bonded to six equivalent Pd2+ atoms to form a mixture of corner and edge-sharing OPd6 octahedra. The corner-sharing octahedral tilt angles are 0°.
