Materials Data on YbCuGe by Materials Project

Abstract

YbCuGe is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Yb is bonded to six equivalent Cu and six equivalent Ge atoms to form a mixture of edge and face-sharing YbCu6Ge6 cuboctahedra. There are three shorter (3.01 Å) and three longer (3.08 Å) Yb–Cu bond lengths. There are three shorter (3.03 Å) and three longer (3.06 Å) Yb–Ge bond lengths. Cu is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Ge atoms. All Cu–Ge bond lengths are 2.49 Å. Ge is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Cu atoms.
