TbCu4Ag crystallizes in the cubic F-43m space group. Tb(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1) and twelve equivalent Cu(1) atoms. Ag(1) is bonded in a 16-coordinate geometry to four equivalent Tb(1) and twelve equivalent Cu(1) atoms. Cu(1) is bonded to three equivalent Tb(1), three equivalent Ag(1), and six equivalent Cu(1) atoms to form a mixture of corner, edge, and face-sharing CuTb3Cu6Ag3 cuboctahedra.
TbCu4Ag crystallizes in the cubic F-43m space group. Tb(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1) and twelve equivalent Cu(1) atoms. All Tb(1)-Ag(1) bond lengths are 3.07 Å. All Tb(1)-Cu(1) bond lengths are 2.94 Å. Ag(1) is bonded in a 16-coordinate geometry to four equivalent Tb(1) and twelve equivalent Cu(1) atoms. All Ag(1)-Cu(1) bond lengths are 2.93 Å. Cu(1) is bonded to three equivalent Tb(1), three equivalent Ag(1), and six equivalent Cu(1) atoms to form a mixture of corner, edge, and face-sharing CuTb3Cu6Ag3 cuboctahedra. There are three shorter (2.48 Å) and three longer (2.53 Å) Cu(1)-Cu(1) bond lengths.
