Materials Data on LaCuPb by Materials Project

LaCuPb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. La is bonded to six equivalent Cu and six equivalent Pb atoms to form a mixture of edge and face-sharing LaCu6Pb6 cuboctahedra. All La–Cu bond lengths are 3.38 Å. All La–Pb bond lengths are 3.38 Å. Cu is bonded in a 3-coordinate geometry to six equivalent La and three equivalent Pb atoms. All Cu–Pb bond lengths are 2.70 Å. Pb is bonded in a 3-coordinate geometry to six equivalent La and three equivalent Cu atoms.

Materials Data on LaCuPb by Materials Project

LaCuPb crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. La is bonded in a 12-coordinate geometry to six equivalent Cu and six equivalent Pb atoms. There are three shorter (3.16 Å) and three longer (3.63 Å) La–Cu bond lengths. There are three shorter (3.29 Å) and three longer (3.48 Å) La–Pb bond lengths. Cu is bonded in a 10-coordinate geometry to six equivalent La and four equivalent Pb atoms. There are three shorter (2.80 Å) and one longer (3.39 Å) Cu–Pb bond lengths. Pb is bonded in a 10-coordinate geometry to six equivalent La and four equivalent Cu atoms.
