The structure described by Y5(Os2Ge5)2 crystallizes in the tetragonal P4/mbm space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 16-coordinate geometry to four equivalent Os(1), four equivalent Ge(2), and eight equivalent Ge(3) atoms. In the second Y site, Y(2) is bonded to four equivalent Os(1), two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms to form distorted face-sharing YGe8Os4 cuboctahedra. In the third Y site, Y(3) is bonded in a 14-coordinate geometry to four equivalent Os(1), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. Os(1) is bonded in a 10-coordinate geometry to one Y(1), two equivalent Y(2), two equivalent Y(3), one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Y(2), four equivalent Y(3), two equivalent Os(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Y(1), two equivalent Y(2), two equivalent Y(3), two equivalent Os(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Y(2), one Y(3), two equivalent Y(1), two equivalent Os(1), and two equivalent Ge(3) atoms. is represented by the CIF file [CIF]
