Materials Data on La5MnPb3 by Materials Project
La5MnPb3 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 to two equivalent Mn and five equivalent Pb atoms to form a mixture of distorted edge, face, and corner-sharing LaMn2Pb5 pentagonal bipyramids. Both La–Mn bond lengths are 3.02 Å. There are a spread of La–Pb bond distances ranging from 3.38–3.80 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 3.49 Å. Mn is bonded to six equivalent La atoms to form face-sharing MnLa6 octahedra. Pb is bonded in a 9-coordinate geometry to nine La atoms.
