TaGeFeGe is High Pressure Cadmuum Telluride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two FeGe clusters and two TaGe clusters. In each FeGe cluster, Fe(1) is bonded in a distorted single-bond geometry to one Ge(2) atom. The Fe(1)-Ge(2) bond length is 0.78 Å. Ge(2) is bonded in a single-bond geometry to one Fe(1) atom. In each TaGe cluster, Ta(1) is bonded in a single-bond geometry to one Ge(1) atom. The Ta(1)-Ge(1) bond length is 1.56 Å. Ge(1) is bonded in a 1-coordinate geometry to one Ta(1) atom.
