FeZnGe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two FeZnGe clusters. Fe(1) is bonded in a distorted single-bond geometry to one Zn(1) atom. The Fe(1)-Zn(1) bond length is 0.93 Å. Zn(1) is bonded in a linear geometry to one Fe(1) and one Ge(1) atom. The Zn(1)-Ge(1) bond length is 1.60 Å. Ge(1) is bonded in a distorted single-bond geometry to one Zn(1) atom.
