YCuGe crystallizes in the trigonal P-3m1 space group. Y(1) is bonded to six equivalent Cu(1) and six equivalent Ge(1) atoms to form a mixture of distorted face and edge-sharing YCu6Ge6 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Y(1) and three equivalent Cu(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Y(1) and three equivalent Ge(1) atoms.
YCuGe crystallizes in the trigonal P-3m1 space group. Y(1) is bonded to six equivalent Cu(1) and six equivalent Ge(1) atoms to form a mixture of distorted face and edge-sharing YCu6Ge6 cuboctahedra. There are three shorter (3.04 Å) and three longer (3.08 Å) Y(1)-Cu(1) bond lengths. There are three shorter (3.05 Å) and three longer (3.30 Å) Y(1)-Ge(1) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Y(1) and three equivalent Cu(1) atoms. All Cu(1)-Cu(1) bond lengths are 2.49 Å. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Y(1) and three equivalent Ge(1) atoms. All Ge(1)-Ge(1) bond lengths are 2.52 Å.
