BaEu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ba(1) is bonded to twelve equivalent Eu(1) atoms to form BaEu12 cuboctahedra that share corners with twelve equivalent Ba(1)Eu12 cuboctahedra, edges with twenty-four equivalent Eu(1)Ba4Eu8 cuboctahedra, faces with six equivalent Ba(1)Eu12 cuboctahedra, and faces with twelve equivalent Eu(1)Ba4Eu8 cuboctahedra. Eu(1) is bonded to four equivalent Ba(1) and eight equivalent Eu(1) atoms to form EuBa4Eu8 cuboctahedra that share corners with twelve equivalent Eu(1)Ba4Eu8 cuboctahedra, edges with eight equivalent Ba(1)Eu12 cuboctahedra, edges with sixteen equivalent Eu(1)Ba4Eu8 cuboctahedra, faces with four equivalent Ba(1)Eu12 cuboctahedra, and faces with fourteen equivalent Eu(1)Ba4Eu8 cuboctahedra.
