Materials Data on Er(Co2Ge)2 by Materials Project
Er(Co2Ge)2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Er is bonded to six equivalent Ge atoms to form a mixture of distorted edge and corner-sharing ErGe6 octahedra. The corner-sharing octahedral tilt angles are 39°. There are two shorter (2.84 Å) and four longer (2.92 Å) Er–Ge bond lengths. Co is bonded in a 3-coordinate geometry to three equivalent Ge atoms. All Co–Ge bond lengths are 2.39 Å. Ge is bonded in a 9-coordinate geometry to three equivalent Er and six equivalent Co atoms.
