Cr Fe Ge
CrFeGe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrFeGe clusters. Cr(1) is bonded in a linear geometry to one Fe(1) and one Ge(1) atom. The Cr(1)-Fe(1) bond length is 0.48 Å. The Cr(1)-Ge(1) bond length is 0.15 Å. Fe(1) is bonded in a single-bond geometry to one Cr(1) atom. Ge(1) is bonded in a single-bond geometry to one Cr(1) atom.
