Materials Data on Sr3Eu by Materials Project
Sr3Eu is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sr is bonded to eight equivalent Sr and four equivalent Eu atoms to form SrSr8Eu4 cuboctahedra that share corners with twelve equivalent SrSr8Eu4 cuboctahedra, edges with eight equivalent EuSr12 cuboctahedra, edges with sixteen equivalent SrSr8Eu4 cuboctahedra, faces with four equivalent EuSr12 cuboctahedra, and faces with fourteen equivalent SrSr8Eu4 cuboctahedra. All Sr–Sr bond lengths are 4.23 Å. All Sr–Eu bond lengths are 4.23 Å. Eu is bonded to twelve equivalent Sr atoms to form EuSr12 cuboctahedra that share corners with twelve equivalent EuSr12 cuboctahedra, edges with twenty-four equivalent SrSr8Eu4 cuboctahedra, faces with six equivalent EuSr12 cuboctahedra, and faces with twelve equivalent SrSr8Eu4 cuboctahedra.
