Materials Data on Ce5NiPb3 by Materials Project
Ce5NiPb3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded to two equivalent Ni and five equivalent Pb atoms to form a mixture of distorted face, edge, and corner-sharing CeNi2Pb5 pentagonal bipyramids. Both Ce–Ni bond lengths are 2.80 Å. There are a spread of Ce–Pb bond distances ranging from 3.31–3.55 Å. In the second Ce site, Ce is bonded in a 6-coordinate geometry to six equivalent Pb atoms. All Ce–Pb bond lengths are 3.36 Å. Ni is bonded to six equivalent Ce atoms to form face-sharing NiCe6 octahedra. Pb is bonded in a 9-coordinate geometry to nine Ce atoms.
