Materials Data on SmPa by Materials Project

Abstract

PaSm 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 Sm atoms to form PaSm6Pa6 cuboctahedra that share corners with eighteen equivalent PaSm6Pa6 cuboctahedra, edges with six equivalent PaSm6Pa6 cuboctahedra, edges with twelve equivalent SmSm6Pa6 cuboctahedra, faces with eight equivalent PaSm6Pa6 cuboctahedra, and faces with twelve equivalent SmSm6Pa6 cuboctahedra. All Pa–Pa bond lengths are 3.31 Å. All Pa–Sm bond lengths are 3.53 Å.
