V Ge Ge Te
VGe2Te crystallizes in the monoclinic Cm space group. V(1) is bonded in a 4-coordinate geometry to one Ge(2) and three equivalent Ge(1) atoms. The V(1)-Ge(2) bond length is 2.95 Å. There is one shorter (2.59 Å) and two longer (3.16 Å) V(1)-Ge(1) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to three equivalent V(1) and one Te(1) atom. The Ge(1)-Te(1) bond length is 2.05 Å. In the second Ge site, Ge(2) is bonded in a 1-coordinate geometry to one V(1) and one Te(1) atom. The Ge(2)-Te(1) bond length is 2.05 Å. Te(1) is bonded in a 2-coordinate geometry to one Ge(1) and one Ge(2) atom.
