MgVGe2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgVGe2 cluster. Mg(1) is bonded in a distorted bent 150 degrees geometry to one V(1) and one Ge(1) atom. The Mg(1)-V(1) bond length is 0.16 Å. The Mg(1)-Ge(1) bond length is 0.90 Å. V(1) is bonded in a distorted single-bond geometry to one Mg(1) and one Ge(2) atom. The V(1)-Ge(2) bond length is 1.31 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one Mg(1) atom. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one V(1) atom.
