Materials Data on EuTh3 by Materials Project

Abstract

Th3Eu is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Th is bonded to eight equivalent Th and four equivalent Eu atoms to form ThEu4Th8 cuboctahedra that share corners with twelve equivalent ThEu4Th8 cuboctahedra, edges with eight equivalent EuTh12 cuboctahedra, edges with sixteen equivalent ThEu4Th8 cuboctahedra, faces with four equivalent EuTh12 cuboctahedra, and faces with fourteen equivalent ThEu4Th8 cuboctahedra. All Th–Th bond lengths are 3.61 Å. All Th–Eu bond lengths are 3.61 Å. Eu is bonded to twelve equivalent Th atoms to form EuTh12 cuboctahedra that share corners with twelve equivalent EuTh12 cuboctahedra, edges with twenty-four equivalent ThEu4Th8 cuboctahedra, faces with six equivalent EuTh12 cuboctahedra, and faces with twelve equivalent ThEu4Th8 cuboctahedra.
