Materials Data on Pa3Si by Materials Project

Abstract

Pa3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pa is bonded to eight equivalent Pa and four equivalent Si atoms to form distorted PaPa8Si4 cuboctahedra that share corners with twelve equivalent PaPa8Si4 cuboctahedra, edges with eight equivalent SiPa12 cuboctahedra, edges with sixteen equivalent PaPa8Si4 cuboctahedra, faces with four equivalent SiPa12 cuboctahedra, and faces with fourteen equivalent PaPa8Si4 cuboctahedra. All Pa–Pa bond lengths are 3.14 Å. All Pa–Si bond lengths are 3.14 Å. Si is bonded to twelve equivalent Pa atoms to form SiPa12 cuboctahedra that share corners with twelve equivalent SiPa12 cuboctahedra, edges with twenty-four equivalent PaPa8Si4 cuboctahedra, faces with six equivalent SiPa12 cuboctahedra, and faces with twelve equivalent PaPa8Si4 cuboctahedra.
