Abstract
Al5Ti3 is alpha La-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are three inequivalent Ti sites. In the first Ti site, Ti is bonded to four equivalent Ti and eight equivalent Al atoms to form TiTi4Al8 cuboctahedra that share corners with four equivalent TiTi4Al8 cuboctahedra, corners with eight equivalent AlTi4Al8 cuboctahedra, edges with eight equivalent TiAl12 cuboctahedra, edges with sixteen equivalent AlTi6Al6 cuboctahedra, faces with eight TiTi4Al8 cuboctahedra, and faces with ten AlTi6Al6 cuboctahedra. All Ti–Ti bond lengths are 2.77 Å. All Ti–Al bond lengths are 2.85 Å. In the second Ti site, Ti is bonded to twelve Al atoms to form TiAl12 cuboctahedra that share corners with twelve TiAl12 cuboctahedra, edges with eight equivalent TiTi4Al8 cuboctahedra, edges with sixteen equivalent AlTi6Al6 cuboctahedra, faces with six TiAl12 cuboctahedra, and faces with twelve AlTi6Al6 cuboctahedra. There are four shorter (2.77 Å) and eight longer (2.88 Å) Ti–Al bond lengths. In the third Ti site, Ti is bonded to four equivalent Ti and eight equivalent Al atoms to form TiTi4Al8 cuboctahedra that share corners with twelve TiAl12 cuboctahedra, edges with twenty-four AlTi6Al6 cuboctahedra, faces with eight equivalent AlTi6Al6 cuboctahedra, and faces with ten TiTi4Al8 cuboctahedra.more »
