MgW2Ge crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgW2Ge cluster. Mg(1) is bonded in a 2-coordinate geometry to one W(1) and one Ge(1) atom. The Mg(1)-W(1) bond length is 1.99 Å. The Mg(1)-Ge(1) bond length is 1.35 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 1-coordinate geometry to one Mg(1) atom. In the second W site, W(2) is bonded in a 1-coordinate geometry to one Ge(1) atom. The W(2)-Ge(1) bond length is 1.99 Å. Ge(1) is bonded in a 1-coordinate geometry to one Mg(1) and one W(2) atom.
