Materials Data on Eu3Th by Materials Project

Abstract

ThEu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Th is bonded to twelve equivalent Eu atoms to form ThEu12 cuboctahedra that share corners with twelve equivalent ThEu12 cuboctahedra, edges with twenty-four equivalent EuEu8Th4 cuboctahedra, faces with six equivalent ThEu12 cuboctahedra, and faces with twelve equivalent EuEu8Th4 cuboctahedra. All Th–Eu bond lengths are 3.80 Å. Eu is bonded to four equivalent Th and eight equivalent Eu atoms to form EuEu8Th4 cuboctahedra that share corners with twelve equivalent EuEu8Th4 cuboctahedra, edges with eight equivalent ThEu12 cuboctahedra, edges with sixteen equivalent EuEu8Th4 cuboctahedra, faces with four equivalent ThEu12 cuboctahedra, and faces with fourteen equivalent EuEu8Th4 cuboctahedra. All Eu–Eu bond lengths are 3.80 Å.
