Materials Data on Er(CuGe)2 by Materials Project
ErCu2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Er is bonded in a 8-coordinate geometry to eight equivalent Cu and eight equivalent Ge atoms. All Er–Cu bond lengths are 3.28 Å. All Er–Ge bond lengths are 3.10 Å. Cu is bonded to four equivalent Er and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing CuEr4Ge4 tetrahedra. All Cu–Ge bond lengths are 2.43 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Er, four equivalent Cu, and one Ge atom. The Ge–Ge bond length is 2.45 Å.
