CoAg2Ge crystallizes in the monoclinic Cm space group. Co(1) is bonded in a distorted single-bond geometry to one Ag(1) and one Ge(1) atom. The Co(1)-Ag(1) bond length is 2.03 Å. The Co(1)-Ge(1) bond length is 0.95 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 1-coordinate geometry to one Co(1) and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 2.38 Å. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to one Ag(1) and three equivalent Ge(1) atoms. There is one shorter (2.64 Å) and two longer (3.05 Å) Ag(2)-Ge(1) bond lengths. Ge(1) is bonded in a single-bond geometry to one Co(1) and three equivalent Ag(2) atoms.
