The material described by BeTi3 is alpha Samarium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Be(1) is bonded to twelve equivalent Ti(1) atoms to form BeTi12 cuboctahedra that share corners with six equivalent Be(1)Ti12 cuboctahedra, corners with twelve equivalent Ti(1)Ti8Be4 cuboctahedra, edges with eighteen equivalent Ti(1)Ti8Be4 cuboctahedra, faces with eight equivalent Be(1)Ti12 cuboctahedra, and faces with twelve equivalent Ti(1)Ti8Be4 cuboctahedra. Ti(1) is bonded to four equivalent Be(1) and eight equivalent Ti(1) atoms to form TiTi8Be4 cuboctahedra that share corners with four equivalent Be(1)Ti12 cuboctahedra, corners with fourteen equivalent Ti(1)Ti8Be4 cuboctahedra, edges with six equivalent Be(1)Ti12 cuboctahedra, edges with twelve equivalent Ti(1)Ti8Be4 cuboctahedra, faces with four equivalent Be(1)Ti12 cuboctahedra, and faces with sixteen equivalent Ti(1)Ti8Be4 cuboctahedra. is represented by the CIF card [CIF]
