TmCuPb crystallizes in the hexagonal P6_3mc space group. Tm(1) is bonded in a 9-coordinate geometry to three equivalent Cu(1) and six equivalent Pb(1) atoms. Cu(1) is bonded in a 7-coordinate geometry to three equivalent Tm(1) and four equivalent Pb(1) atoms. Pb(1) is bonded in a 10-coordinate geometry to six equivalent Tm(1) and four equivalent Cu(1) atoms.
TmCuPb crystallizes in the hexagonal P6_3mc space group. Tm(1) is bonded in a 9-coordinate geometry to three equivalent Cu(1) and six equivalent Pb(1) atoms. All Tm(1)-Cu(1) bond lengths are 2.88 Å. There are three shorter (3.11 Å) and three longer (3.27 Å) Tm(1)-Pb(1) bond lengths. Cu(1) is bonded in a 7-coordinate geometry to three equivalent Tm(1) and four equivalent Pb(1) atoms. There are three shorter (2.73 Å) and one longer (2.88 Å) Cu(1)-Pb(1) bond length. Pb(1) is bonded in a 10-coordinate geometry to six equivalent Tm(1) and four equivalent Cu(1) atoms.
