Be3Ti2Ga crystallizes in the trigonal R-3m space group. Be(1) is bonded to four equivalent Be(1), six equivalent Ti(1), and two equivalent Ga(1) atoms to form distorted BeTi6Be4Ga2 cuboctahedra that share corners with four equivalent Ga(1)Ti6Be6 cuboctahedra, corners with fourteen equivalent Be(1)Ti6Be4Ga2 cuboctahedra, edges with six equivalent Be(1)Ti6Be4Ga2 cuboctahedra, faces with six equivalent Ga(1)Ti6Be6 cuboctahedra, and faces with twelve equivalent Be(1)Ti6Be4Ga2 cuboctahedra. Ti(1) is bonded in a 16-coordinate geometry to nine equivalent Be(1), four equivalent Ti(1), and three equivalent Ga(1) atoms. Ga(1) is bonded to six equivalent Be(1) and six equivalent Ti(1) atoms to form GaTi6Be6 cuboctahedra that share corners with six equivalent Ga(1)Ti6Be6 cuboctahedra, corners with twelve equivalent Be(1)Ti6Be4Ga2 cuboctahedra, edges with six equivalent Ga(1)Ti6Be6 cuboctahedra, and faces with eighteen equivalent Be(1)Ti6Be4Ga2 cuboctahedra.
