Materials Data on PaCd by Materials Project

Abstract

PaCd is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Pa is bonded to six equivalent Pa and six equivalent Cd atoms to form PaPa6Cd6 cuboctahedra that share corners with eighteen equivalent PaPa6Cd6 cuboctahedra, edges with six equivalent PaPa6Cd6 cuboctahedra, edges with twelve equivalent CdPa6Cd6 cuboctahedra, faces with eight equivalent PaPa6Cd6 cuboctahedra, and faces with twelve equivalent CdPa6Cd6 cuboctahedra. All Pa–Pa bond lengths are 3.12 Å. All Pa–Cd bond lengths are 3.40 Å. Cd is bonded to six equivalent Pa and six equivalent Cd atoms to form CdPa6Cd6 cuboctahedra that share corners with eighteen equivalent CdPa6Cd6 cuboctahedra, edges with six equivalent CdPa6Cd6 cuboctahedra, edges with twelve equivalent PaPa6Cd6 cuboctahedra, faces with eight equivalent CdPa6Cd6 cuboctahedra, and faces with twelve equivalent PaPa6Cd6 cuboctahedra. All Cd–Cd bond lengths are 3.12 Å.
