The structure described by Ti6Ge5 crystallizes in the monoclinic C2/m space group. There are five inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to one Ge(2), one Ge(3), two equivalent Ge(5), and three equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing TiGe7 pentagonal bipyramids. In the second Ti site, Ti(2) is bonded to one Ge(1), one Ge(4), two equivalent Ge(5), and three equivalent Ge(2) atoms to form a mixture of distorted face, corner, and edge-sharing TiGe7 pentagonal bipyramids. In the third Ti site, Ti(3) is bonded in a 7-coordinate geometry to one Ge(1), two equivalent Ge(3), two equivalent Ge(4), and two equivalent Ge(5) atoms. In the fourth Ti site, Ti(4) is bonded in a 7-coordinate geometry to one Ge(2), two equivalent Ge(3), two equivalent Ge(4), and two equivalent Ge(5) atoms. In the fifth Ti site, Ti(5) is bonded in a 6-coordinate geometry to one Ge(3), one Ge(4), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(5) is bonded in a 10-coordinate geometry to two equivalent Ti(1), two equivalent Ti(2), two equivalent Ti(3), two equivalent Ti(4), and two equivalent Ge(5) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Ti(2), one Ti(3), three equivalent Ti(1), and four equivalent Ti(5) atoms. In the third Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Ti(1), one Ti(4), three equivalent Ti(2), and four equivalent Ti(5) atoms. In the fourth Ge site, Ge(3) is bonded in a 7-coordinate geometry to one Ti(1), two equivalent Ti(3), two equivalent Ti(4), and two equivalent Ti(5) atoms. In the fifth Ge site, Ge(4) is bonded in a 7-coordinate geometry to one Ti(2), two equivalent Ti(3), two equivalent Ti(4), and two equivalent Ti(5) atoms. is represented by the CIF file [CIF]
