Materials Data on Li2PdO3 by Materials Project
Li2PdO3 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with four equivalent PdO6 octahedra, edges with four equivalent PdO6 octahedra, and edges with eight LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–6°. There are two shorter (2.08 Å) and four longer (2.20 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with four equivalent PdO6 octahedra, edges with four equivalent PdO6 octahedra, and edges with eight LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–6°. There are a spread of Li–O bond distances ranging from 2.10–2.21 Å. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six LiO6 octahedra, edges with six LiO6 octahedra, and edges with six equivalent PdO6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are four shorter (2.13 Å) and two longer (2.14 Å) Li–O bond lengths. Pd4+ is bonded to six O2- atoms to form PdO6 octahedra that share corners with six LiO6 octahedra, edges with three equivalent PdO6 octahedra, and edges with nine LiO6 octahedra. The corner-sharing octahedral tilt angles are 4°. There are four shorter (2.04 Å) and two longer (2.05 Å) Pd–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four Li1+ and two equivalent Pd4+ atoms to form a mixture of edge and corner-sharing OLi4Pd2 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. In the second O2- site, O2- is bonded to four Li1+ and two equivalent Pd4+ atoms to form a mixture of edge and corner-sharing OLi4Pd2 octahedra. The corner-sharing octahedra tilt angles range from 0–4°.
