Materials Data on CePr3 by Materials Project

Abstract

Pr3Ce is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Pr is bonded to eight equivalent Pr and four equivalent Ce atoms to form PrCe4Pr8 cuboctahedra that share corners with twelve equivalent PrCe4Pr8 cuboctahedra, edges with eight equivalent CePr12 cuboctahedra, edges with sixteen equivalent PrCe4Pr8 cuboctahedra, faces with four equivalent CePr12 cuboctahedra, and faces with fourteen equivalent PrCe4Pr8 cuboctahedra. All Pr–Pr bond lengths are 3.69 Å. All Pr–Ce bond lengths are 3.69 Å. Ce is bonded to twelve equivalent Pr atoms to form CePr12 cuboctahedra that share corners with twelve equivalent CePr12 cuboctahedra, edges with twenty-four equivalent PrCe4Pr8 cuboctahedra, faces with six equivalent CePr12 cuboctahedra, and faces with twelve equivalent PrCe4Pr8 cuboctahedra.
