Materials Data on CsPdBr3 by Materials Project

CsPdBr3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Cs1+ is bonded to twelve Br1- atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent CsBr12 cuboctahedra, faces with six equivalent CsBr12 cuboctahedra, and faces with eight equivalent PdBr6 octahedra. There are a spread of Cs–Br bond distances ranging from 3.74–3.80 Å. Pd2+ is bonded to six Br1- atoms to form PdBr6 octahedra that share corners with six equivalent PdBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. All Pd–Br bond lengths are 2.67 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded to four equivalent Cs1+ and two equivalent Pd2+ atoms to form a mixture of distorted corner, edge, and face-sharing BrCs4Pd2 octahedra. The corner-sharing octahedra tilt angles range from 0–61°. In the second Br1- site, Br1- is bonded to four equivalent Cs1+ and two equivalent Pd2+ atoms to form a mixture of distorted corner, edge, and face-sharing BrCs4Pd2 octahedra. The corner-sharing octahedra tilt angles range from 1–61°. In the third Br1- site, Br1- is bonded to four equivalent Cs1+ and two equivalent Pd2+ atoms to form a mixture of distorted corner, edge, and face-sharing BrCs4Pd2 octahedra. The corner-sharing octahedra tilt angles range from 1–61°.

Materials Data on Cs2PdBr6 by Materials Project

Cs2PdBr6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent Br1- atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent CsBr12 cuboctahedra, faces with six equivalent CsBr12 cuboctahedra, and faces with four equivalent PdBr6 octahedra. All Cs–Br bond lengths are 3.89 Å. Pd4+ is bonded to six equivalent Br1- atoms to form PdBr6 octahedra that share faces with eight equivalent CsBr12 cuboctahedra. All Pd–Br bond lengths are 2.52 Å. Br1- is bonded in a distorted single-bond geometry to four equivalent Cs1+ and one Pd4+ atom.
