Materials Data on La5CoPb3 by Materials Project

La5CoPb3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 7-coordinate geometry to two equivalent Co and five equivalent Pb atoms. Both La–Co bond lengths are 2.87 Å. There are a spread of La–Pb bond distances ranging from 3.40–3.97 Å. In the second La site, La is bonded in a 6-coordinate geometry to six equivalent Pb atoms. All La–Pb bond lengths are 3.45 Å. Co is bonded to six equivalent La atoms to form face-sharing CoLa6 octahedra. Pb is bonded in a 9-coordinate geometry to nine La atoms.
