FeCdGe2 crystallizes in the triclinic P1 space group. Fe(1) is bonded to one Cd(1) and four equivalent Ge(2) atoms to form a mixture of corner and edge-sharing FeCdGe4 square pyramids. The Fe(1)-Cd(1) bond length is 2.21 Å. There are a spread of Fe(1)-Ge(2) bond distances ranging from 2.03-2.29 Å. Cd(1) is bonded in a distorted single-bond geometry to one Fe(1) and four equivalent Ge(1) atoms. There are a spread of Cd(1)-Ge(1) bond distances ranging from 3.06-3.24 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Cd(1), one Ge(2), and four equivalent Ge(1) atoms. The Ge(1)-Ge(2) bond length is 2.83 Å. There are two shorter (2.99 Å) and two longer (3.11 Å) Ge(1)-Ge(1) bond lengths. In the second Ge site, Ge(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Fe(1) and one Ge(1) atom.
