Materials Data on LuMn5 by Materials Project

Abstract

LuMn5 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Lu is bonded in a 12-coordinate geometry to sixteen Mn atoms. There are a spread of Lu–Mn bond distances ranging from 2.81–2.98 Å. There are three inequivalent Mn sites. In the first Mn site, Mn is bonded to three equivalent Lu and nine Mn atoms to form a mixture of distorted corner, edge, and face-sharing MnLu3Mn9 cuboctahedra. There are a spread of Mn–Mn bond distances ranging from 2.36–2.89 Å. In the second Mn site, Mn is bonded to three equivalent Lu and nine Mn atoms to form a mixture of corner, edge, and face-sharing MnLu3Mn9 cuboctahedra. All Mn–Mn bond lengths are 2.86 Å. In the third Mn site, Mn is bonded in a 4-coordinate geometry to four equivalent Lu and twelve Mn atoms.
