Materials Data on La5NiPb3 by Materials Project

Abstract

La5NiPb3 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 Ni and five equivalent Pb atoms. Both La–Ni bond lengths are 2.92 Å. There are a spread of La–Pb bond distances ranging from 3.38–3.93 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. Ni is bonded to six equivalent La atoms to form face-sharing NiLa6 octahedra. Pb is bonded in a 9-coordinate geometry to nine La atoms.
