Materials Data on Ba3Al2Cu2F16 by Materials Project
Abstract
Ba3Cu2Al2F16 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to twelve F1- atoms. There are a spread of Ba–F bond distances ranging from 2.71–3.19 Å. In the second Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to eleven F1- atoms. There are a spread of Ba–F bond distances ranging from 2.65–3.27 Å. In the third Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Ba–F bond distances ranging from 2.66–3.14 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six F1- atoms to form distorted CuF6 octahedra that share corners with two equivalent AlF6 octahedra and edges with two equivalent CuF6 octahedra. The corner-sharing octahedra tilt angles range from 53–55°. There are a spread of Cu–F bond distances ranging from 1.91–2.38 Å. In the second Cu2+ site, Cu2+ is bonded to six F1- atoms to form distorted CuF6 octahedra that share corners with two equivalent AlF6 octahedra and edges with two equivalent CuF6 octahedra. The corner-sharing octahedra tilt angles range from 51–59°.more »
