Materials Data on Ti2Ag by Materials Project
Ti2Ag crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ti is bonded to eight equivalent Ti and four equivalent Ag atoms to form distorted TiTi8Ag4 cuboctahedra that share corners with four equivalent AgTi8Ag4 cuboctahedra, corners with eight equivalent TiTi8Ag4 cuboctahedra, edges with twelve equivalent TiTi8Ag4 cuboctahedra, edges with twelve equivalent AgTi8Ag4 cuboctahedra, faces with five equivalent AgTi8Ag4 cuboctahedra, and faces with thirteen equivalent TiTi8Ag4 cuboctahedra. There are four shorter (2.80 Å) and four longer (2.93 Å) Ti–Ti bond lengths. All Ti–Ag bond lengths are 2.95 Å. Ag is bonded to eight equivalent Ti and four equivalent Ag atoms to form AgTi8Ag4 cuboctahedra that share corners with four equivalent AgTi8Ag4 cuboctahedra, corners with eight equivalent TiTi8Ag4 cuboctahedra, edges with twenty-four equivalent TiTi8Ag4 cuboctahedra, faces with eight equivalent AgTi8Ag4 cuboctahedra, and faces with ten equivalent TiTi8Ag4 cuboctahedra. All Ag–Ag bond lengths are 2.93 Å.
