V V Fe Ge
V2FeGe crystallizes in the monoclinic Cm space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 4-coordinate geometry to one V(2) and four equivalent Fe(1) atoms. The V(1)-V(2) bond length is 1.48 Å. There are a spread of V(1)-Fe(1) bond distances ranging from 1.88-2.64 Å. In the second V site, V(2) is bonded in a 1-coordinate geometry to one V(1), four equivalent Fe(1), and one Ge(1) atom. There are a spread of V(2)-Fe(1) bond distances ranging from 2.21-2.88 Å. The V(2)-Ge(1) bond length is 2.62 Å. Fe(1) is bonded in a 10-coordinate geometry to four equivalent V(1), four equivalent V(2), and two equivalent Ge(1) atoms. There is one shorter (2.14 Å) and one longer (3.03 Å) Fe(1)-Ge(1) bond length. Ge(1) is bonded in a 2-coordinate geometry to one V(2) and two equivalent Fe(1) atoms.
