Materials Data on K3Al4P2O8F9 by Materials Project
Abstract
K3Al4P2O8F9 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 7-coordinate geometry to three O2- and four F1- atoms. There are one shorter (2.88 Å) and two longer (2.99 Å) K–O bond lengths. There are a spread of K–F bond distances ranging from 2.69–3.27 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to four O2- and five F1- atoms. There are two shorter (2.82 Å) and two longer (3.17 Å) K–O bond lengths. There are a spread of K–F bond distances ranging from 2.74–3.11 Å. There are three inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to two O2- and four F1- atoms to form AlO2F4 octahedra that share corners with three AlO2F4 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 33–35°. Both Al–O bond lengths are 1.86 Å. There are a spread of Al–F bond distances ranging from 1.79–1.91 Å. In the second Al3+ site, Al3+ is bonded to two equivalent O2- and four F1- atoms to form AlO2F4 octahedra that share corners with four AlO2F4more »
