Materials Data on Pa3Re by Materials Project
Pa3Re is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pa is bonded to eight equivalent Pa and four equivalent Re atoms to form distorted PaPa8Re4 cuboctahedra that share corners with four equivalent RePa12 cuboctahedra, corners with fourteen equivalent PaPa8Re4 cuboctahedra, edges with six equivalent RePa12 cuboctahedra, edges with twelve equivalent PaPa8Re4 cuboctahedra, faces with four equivalent RePa12 cuboctahedra, and faces with sixteen equivalent PaPa8Re4 cuboctahedra. There are a spread of Pa–Pa bond distances ranging from 2.92–3.30 Å. There are two shorter (3.10 Å) and two longer (3.18 Å) Pa–Re bond lengths. Re is bonded to twelve equivalent Pa atoms to form RePa12 cuboctahedra that share corners with six equivalent RePa12 cuboctahedra, corners with twelve equivalent PaPa8Re4 cuboctahedra, edges with eighteen equivalent PaPa8Re4 cuboctahedra, faces with eight equivalent RePa12 cuboctahedra, and faces with twelve equivalent PaPa8Re4 cuboctahedra.
