W2AgGe crystallizes in the triclinic P1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one Ag(1) and two equivalent Ge(1) atoms. The W(1)-Ag(1) bond length is 3.74 Å. There is one shorter (1.37 Å) and one longer (1.91 Å) W(1)-Ge(1) bond length. In the second W site, W(2) is bonded in a 2-coordinate geometry to one Ag(1) and two equivalent Ge(1) atoms. The W(2)-Ag(1) bond length is 3.74 Å. There is one shorter (1.45 Å) and one longer (1.96 Å) W(2)-Ge(1) bond length. Ag(1) is bonded in a 8-coordinate geometry to one W(1), one W(2), and six equivalent Ag(1) atoms. There are four shorter (2.78 Å) and two longer (3.23 Å) Ag(1)-Ag(1) bond lengths. Ge(1) is bonded in a 4-coordinate geometry to two equivalent W(1) and two equivalent W(2) atoms.
