Ti2MnGe crystallizes in the cubic F-43m space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to four equivalent Ti(2) and four equivalent Ge(1) atoms to form distorted edge-sharing TiTi4Ge4 tetrahedra. In the second Ti site, Ti(2) is bonded in a 14-coordinate geometry to four equivalent Ti(1), four equivalent Mn(1), and six equivalent Ge(1) atoms. Mn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ti(2) and four equivalent Ge(1) atoms. Ge(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ti(1), six equivalent Ti(2), and four equivalent Mn(1) atoms.
