Materials Data on LuZr3F15 by Materials Project

LuZr3F15 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Lu3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Lu–F bond distances ranging from 2.21–2.30 Å. There are two inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded in an octahedral geometry to six F1- atoms. There are two shorter (2.02 Å) and four longer (2.05 Å) Zr–F bond lengths. In the second Zr4+ site, Zr4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Zr–F bond distances ranging from 2.07–2.27 Å. There are eight inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to one Lu3+ and one Zr4+ atom. In the second F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Zr4+ atoms. In the third F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Zr4+ atoms. In the fourth F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Zr4+ atoms. In the fifth F1- site, F1- is bonded in a bent 150 degrees geometry to one Lu3+ and one Zr4+ atom. In the sixth F1- site, F1- is bonded in a bent 150 degrees geometry to one Lu3+ and one Zr4+ atom. In the seventh F1- site, F1- is bonded in a linear geometry to two equivalent Zr4+ atoms. In the eighth F1- site, F1- is bonded in a linear geometry to one Lu3+ and one Zr4+ atom.
