Materials Data on Ba3Pm by Materials Project

Abstract

Ba3Pm is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ba is bonded to eight equivalent Ba and four equivalent Pm atoms to form BaBa8Pm4 cuboctahedra that share corners with twelve equivalent BaBa8Pm4 cuboctahedra, edges with eight equivalent PmBa12 cuboctahedra, edges with sixteen equivalent BaBa8Pm4 cuboctahedra, faces with four equivalent PmBa12 cuboctahedra, and faces with fourteen equivalent BaBa8Pm4 cuboctahedra. All Ba–Ba bond lengths are 4.20 Å. All Ba–Pm bond lengths are 4.20 Å. Pm is bonded to twelve equivalent Ba atoms to form PmBa12 cuboctahedra that share corners with twelve equivalent PmBa12 cuboctahedra, edges with twenty-four equivalent BaBa8Pm4 cuboctahedra, faces with six equivalent PmBa12 cuboctahedra, and faces with twelve equivalent BaBa8Pm4 cuboctahedra.
