description: La6Zr8F47 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are four inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to seven F1- atoms to form distorted LaF7 pentagonal bipyramids that share corners with five ZrF6 octahedra and corners with two equivalent ZrF6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 13–30°. There are a spread of La–F bond distances ranging from 2.30–2.47 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of La–F bond distances ranging from 2.36–2.53 Å. In the third La3+ site, La3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of La–F bond distances ranging from 2.41–2.50 Å. In the fourth La3+ site, La3+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of La–F bond distances ranging from 2.38–2.47 Å. There are four inequivalent Zr+3.62+ sites. In the first Zr+3.62+ site, Zr+3.62+ is bonded to six F1- atoms to form distorted ZrF6 pentagonal pyramids that share corners with two equivalent LaF7 pentagonal bipyramids.
