Materials Data on NaYPO4F by Materials Project
Abstract
NaYPO4F crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to four O2- and two equivalent F1- atoms. There are two shorter (2.52 Å) and two longer (2.64 Å) Na–O bond lengths. Both Na–F bond lengths are 2.46 Å. Y3+ is bonded in a 8-coordinate geometry to six O2- and two equivalent F1- atoms. There are a spread of Y–O bond distances ranging from 2.31–2.47 Å. Both Y–F bond lengths are 2.30 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Y3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Na1+, one Y3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Y3+ and one P5+ atom. F1- is bonded to two equivalent Na1+ and two equivalent Y3+ atoms to form distorted edge-sharing FNa2Y2 tetrahedra.
