The material described by Y11Ge10 is delta Molybdenum Boride-like structured and crystallizes in the tetragonal I4/mmm space group. There are four inequivalent Y sites. In the first Y site, Y(1) is bonded in a 8-coordinate geometry to four equivalent Ge(1) and four equivalent Ge(3) atoms. In the second Y site, Y(2) is bonded in a 7-coordinate geometry to one Ge(3), two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(5) atoms. In the third Y site, Y(3) is bonded in a 7-coordinate geometry to one Ge(4), two equivalent Ge(1), two equivalent Ge(3), and two equivalent Ge(5) atoms. In the fourth Y site, Y(4) is bonded to one Ge(2), one Ge(4), one Ge(5), and four equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing YGe7 pentagonal bipyramids. There are five inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Y(1), one Y(2), two equivalent Y(3), four equivalent Y(4), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Y(2) and four equivalent Y(4) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to one Y(2), two equivalent Y(1), four equivalent Y(3), and two equivalent Ge(3) atoms. In the fourth Ge site, Ge(4) is bonded in a 8-coordinate geometry to four equivalent Y(3) and four equivalent Y(4) atoms. In the fifth Ge site, Ge(5) is bonded in a 8-coordinate geometry to two equivalent Y(2), two equivalent Y(4), and four equivalent Y(3) atoms. is represented by the CIF file [CIF]
