Ti4AlGe7 is Zirconium Disilicide-derived structured and crystallizes in the tetragonal I-4m2 space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 10-coordinate geometry to two equivalent Al(1), two equivalent Ge(2), two equivalent Ge(4), and four equivalent Ge(1) atoms. In the second Ti site, Ti(2) is bonded in a 10-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(5), and four equivalent Ge(2) atoms. Al(1) is bonded in a distorted square co-planar geometry to four equivalent Ti(1) and four equivalent Ge(4) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to two equivalent Ti(2), four equivalent Ti(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Ti(1), four equivalent Ti(2), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to four equivalent Ti(2) and four equivalent Ge(5) atoms. In the fourth Ge site, Ge(4) is bonded in a 8-coordinate geometry to four equivalent Ti(1) and four equivalent Al(1) atoms.
