Materials Data on ErCuGe by Materials Project

ErCuGe crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Er is bonded in a 12-coordinate geometry to six equivalent Cu and six equivalent Ge atoms. There are three shorter (2.88 Å) and three longer (3.19 Å) Er–Cu bond lengths. There are three shorter (2.92 Å) and three longer (3.15 Å) Er–Ge bond lengths. Cu is bonded in a 10-coordinate geometry to six equivalent Er and four equivalent Ge atoms. There are three shorter (2.50 Å) and one longer (3.09 Å) Cu–Ge bond lengths. Ge is bonded in a 10-coordinate geometry to six equivalent Er and four equivalent Cu atoms.

Materials Data on ErCuGe by Materials Project

ErCuGe crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Er is bonded to six equivalent Cu and six equivalent Ge atoms to form a mixture of distorted face and edge-sharing ErCu6Ge6 cuboctahedra. There are three shorter (2.94 Å) and three longer (3.12 Å) Er–Cu bond lengths. There are three shorter (2.99 Å) and three longer (3.28 Å) Er–Ge bond lengths. Cu is bonded in a 10-coordinate geometry to six equivalent Er, three equivalent Cu, and one Ge atom. All Cu–Cu bond lengths are 2.52 Å. The Cu–Ge bond length is 3.19 Å. Ge is bonded in a 10-coordinate geometry to six equivalent Er, one Cu, and three equivalent Ge atoms. All Ge–Ge bond lengths are 2.55 Å.
