Ag2GeSb crystallizes in the monoclinic Cm space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 8-coordinate geometry to one Ag(2), four equivalent Ag(1), and three equivalent Sb(1) atoms. The Ag(1)-Ag(2) bond length is 3.23 Å. All Ag(1)-Ag(1) bond lengths are 3.16 Å. There is one shorter (3.18 Å) and two longer (3.42 Å) Ag(1)-Sb(1) bond lengths. In the second Ag site, Ag(2) is bonded in a 5-coordinate geometry to one Ag(1) and four equivalent Ge(1) atoms. There are a spread of Ag(2)-Ge(1) bond distances ranging from 2.17-2.81 Å. Ge(1) is bonded in a 5-coordinate geometry to four equivalent Ag(2) and one Sb(1) atom. The Ge(1)-Sb(1) bond length is 1.47 Å. Sb(1) is bonded in a single-bond geometry to three equivalent Ag(1) and one Ge(1) atom.
