TbCuGe crystallizes in the hexagonal P6_3mc space group. Tb(1) is bonded to six equivalent Cu(1) and six equivalent Ge(1) atoms to form a mixture of distorted edge and face-sharing TbCu6Ge6 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Cu(1) atoms.
TbCuGe crystallizes in the hexagonal P6_3mc space group. Tb(1) is bonded to six equivalent Cu(1) and six equivalent Ge(1) atoms to form a mixture of distorted edge and face-sharing TbCu6Ge6 cuboctahedra. There are three shorter (2.95 Å) and three longer (3.17 Å) Tb(1)-Cu(1) bond lengths. There are three shorter (2.97 Å) and three longer (3.15 Å) Tb(1)-Ge(1) bond lengths. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Ge(1) atoms. All Cu(1)-Ge(1) bond lengths are 2.46 Å. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Cu(1) atoms.
