Materials Data on CsPm by Materials Project
CsPm is Copper-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are three inequivalent Cs sites. In the first Cs site, Cs is bonded to six equivalent Cs and six equivalent Pm atoms to form CsCs6Pm6 cuboctahedra that share corners with twelve CsCs6Pm6 cuboctahedra, edges with twelve CsCs6Pm6 cuboctahedra, edges with twelve equivalent PmCs6Pm6 cuboctahedra, faces with six equivalent CsCs6Pm6 cuboctahedra, and faces with twelve equivalent PmCs6Pm6 cuboctahedra. All Cs–Cs bond lengths are 3.89 Å. All Cs–Pm bond lengths are 4.45 Å. In the second Cs site, Cs is bonded to six equivalent Cs and six Pm atoms to form CsCs6Pm6 cuboctahedra that share corners with five equivalent PmCs6Pm10 cuboctahedra, corners with twelve CsCs6Pm6 cuboctahedra, edges with ten PmCs6Pm6 cuboctahedra, edges with twelve CsCs6Pm6 cuboctahedra, faces with six equivalent CsCs6Pm6 cuboctahedra, and faces with fifteen PmCs6Pm6 cuboctahedra. All Cs–Cs bond lengths are 3.89 Å. All Cs–Pm bond lengths are 4.45 Å. In the third Cs site, Cs is bonded to six equivalent Cs and six Pm atoms to form CsCs6Pm6 cuboctahedra that share corners with five equivalent PmCs6Pm10 cuboctahedra, corners with twelve CsCs6Pm6 cuboctahedra, edges with ten PmCs6Pm6 cuboctahedra, edges with twelve CsCs6Pm6 cuboctahedra, faces with six equivalent CsCs6Pm6 cuboctahedra, and faces with fifteen PmCs6Pm6 cuboctahedra. All Cs–Cs bond lengths are 3.89 Å. All Cs–Pm bond lengths are 4.45 Å. There are two inequivalent Pm sites. In the first Pm site, Pm is bonded to six Cs and six equivalent Pm atoms to form PmCs6Pm6 cuboctahedra that share corners with twelve PmCs6Pm6 cuboctahedra, edges with twelve CsCs6Pm6 cuboctahedra, edges with twelve PmCs6Pm6 cuboctahedra, faces with six equivalent PmCs6Pm6 cuboctahedra, and faces with twelve CsCs6Pm6 cuboctahedra. All Pm–Pm bond lengths are 3.89 Å. In the second Pm site, Pm is bonded to six Cs and ten equivalent Pm atoms to form PmCs6Pm10 cuboctahedra that share corners with ten CsCs6Pm6 cuboctahedra, corners with twelve PmCs6Pm6 cuboctahedra, edges with eight CsCs6Pm6 cuboctahedra, edges with sixteen PmCs6Pm6 cuboctahedra, faces with sixteen equivalent PmCs6Pm10 cuboctahedra, and faces with eighteen CsCs6Pm6 cuboctahedra. There are a spread of Pm–Pm bond distances ranging from 3.89–7.77 Å.
