The material described by Ca3Eu is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ca(1) is bonded to eight equivalent Ca(1) and four equivalent Eu(1) atoms to form CaCa8Eu4 cuboctahedra that share corners with twelve equivalent Ca(1)Ca8Eu4 cuboctahedra, edges with eight equivalent Eu(1)Ca12 cuboctahedra, edges with sixteen equivalent Ca(1)Ca8Eu4 cuboctahedra, faces with four equivalent Eu(1)Ca12 cuboctahedra, and faces with fourteen equivalent Ca(1)Ca8Eu4 cuboctahedra. Eu(1) is bonded to twelve equivalent Ca(1) atoms to form EuCa12 cuboctahedra that share corners with twelve equivalent Eu(1)Ca12 cuboctahedra, edges with twenty-four equivalent Ca(1)Ca8Eu4 cuboctahedra, faces with six equivalent Eu(1)Ca12 cuboctahedra, and faces with twelve equivalent Ca(1)Ca8Eu4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
