Materials Data on SrEu by Materials Project

Abstract

Eu(Sr1) crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Sr is bonded to six equivalent Sr and six equivalent Eu atoms to form SrSr6Eu6 cuboctahedra that share corners with eighteen equivalent SrSr6Eu6 cuboctahedra, edges with six equivalent SrSr6Eu6 cuboctahedra, edges with twelve equivalent EuSr6Eu6 cuboctahedra, faces with eight equivalent SrSr6Eu6 cuboctahedra, and faces with twelve equivalent EuSr6Eu6 cuboctahedra. All Sr–Sr bond lengths are 4.11 Å. All Sr–Eu bond lengths are 4.14 Å.
