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.
