The structure described by Ag8GeSe6 crystallizes in the orthorhombic Pmn2_1 space group. There are five inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to one Se(2), one Se(3), and one Se(4) atom. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one Se(1), one Se(3), one Se(4), and one Se(5) atom. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to one Se(1), one Se(2), and one Se(4) atom. In the fourth Ag site, Ag(4) is bonded in a 4-coordinate geometry to one Se(1), one Se(3), one Se(4), and one Se(5) atom. In the fifth Ag site, Ag(5) is bonded in a 4-coordinate geometry to one Se(4), one Se(5), and two equivalent Se(1) atoms. Ge(1) is bonded in a tetrahedral geometry to one Se(2), one Se(3), and two equivalent Se(1) atoms. There are five inequivalent Se sites. In the first Se site, Se(1) is bonded in a 5-coordinate geometry to one Ag(2), one Ag(3), one Ag(4), one Ag(5), and one Ge(1) atom. In the second Se site, Se(2) is bonded in a distorted tetrahedral geometry to one Ag(1), two equivalent Ag(3), and one Ge(1) atom.
