Materials Data on Ti2Be3Ga by Materials Project
Be3Ti2Ga crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Be is bonded to four equivalent Be, six equivalent Ti, and two equivalent Ga atoms to form distorted BeTi6Be4Ga2 cuboctahedra that share corners with four equivalent GaTi6Be6 cuboctahedra, corners with fourteen equivalent BeTi6Be4Ga2 cuboctahedra, edges with six equivalent BeTi6Be4Ga2 cuboctahedra, faces with six equivalent GaTi6Be6 cuboctahedra, and faces with twelve equivalent BeTi6Be4Ga2 cuboctahedra. All Be–Be bond lengths are 2.33 Å. There are four shorter (2.74 Å) and two longer (2.77 Å) Be–Ti bond lengths. Both Be–Ga bond lengths are 2.36 Å. Ti is bonded in a 3-coordinate geometry to nine equivalent Be, four equivalent Ti, and three equivalent Ga atoms. There are three shorter (2.86 Å) and one longer (2.90 Å) Ti–Ti bond lengths. All Ti–Ga bond lengths are 2.73 Å. Ga is bonded to six equivalent Be and six equivalent Ti atoms to form GaTi6Be6 cuboctahedra that share corners with six equivalent GaTi6Be6 cuboctahedra, corners with twelve equivalent BeTi6Be4Ga2 cuboctahedra, edges with six equivalent GaTi6Be6 cuboctahedra, and faces with eighteen equivalent BeTi6Be4Ga2 cuboctahedra.
