Sr3Eu is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sr(1) is bonded to eight equivalent Sr(1) and four equivalent Eu(1) atoms to form SrSr8Eu4 cuboctahedra that share corners with twelve equivalent Sr(1)Sr8Eu4 cuboctahedra, edges with eight equivalent Eu(1)Sr12 cuboctahedra, edges with sixteen equivalent Sr(1)Sr8Eu4 cuboctahedra, faces with four equivalent Eu(1)Sr12 cuboctahedra, and faces with fourteen equivalent Sr(1)Sr8Eu4 cuboctahedra. Eu(1) is bonded to twelve equivalent Sr(1) atoms to form EuSr12 cuboctahedra that share corners with twelve equivalent Eu(1)Sr12 cuboctahedra, edges with twenty-four equivalent Sr(1)Sr8Eu4 cuboctahedra, faces with six equivalent Eu(1)Sr12 cuboctahedra, and faces with twelve equivalent Sr(1)Sr8Eu4 cuboctahedra.
