Materials Data on HoCuPb by Materials Project
HoCuPb crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Ho is bonded in a 12-coordinate geometry to three equivalent Cu and six equivalent Pb atoms. All Ho–Cu bond lengths are 2.94 Å. There are three shorter (3.16 Å) and three longer (3.31 Å) Ho–Pb bond lengths. Cu is bonded in a 10-coordinate geometry to three equivalent Ho and four equivalent Pb atoms. There are three shorter (2.76 Å) and one longer (2.95 Å) Cu–Pb bond lengths. Pb is bonded in a 10-coordinate geometry to six equivalent Ho and four equivalent Cu atoms.
