Materials Data on TbCuPb by Materials Project
TbCuPb crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Tb is bonded in a 12-coordinate geometry to six equivalent Cu and six equivalent Pb atoms. There are three shorter (2.97 Å) and three longer (3.60 Å) Tb–Cu bond lengths. There are three shorter (3.17 Å) and three longer (3.34 Å) Tb–Pb bond lengths. Cu is bonded in a 10-coordinate geometry to six equivalent Tb and four equivalent Pb atoms. There are three shorter (2.76 Å) and one longer (3.01 Å) Cu–Pb bond lengths. Pb is bonded in a 10-coordinate geometry to six equivalent Tb and four equivalent Cu atoms.
