Title: Materials Data on CeAsN(O2F)2 by Materials Project

Abstract

(CeAs(O2F)2)2N2 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional and consists of two ammonia molecules and one CeAs(O2F)2 framework. In the CeAs(O2F)2 framework, Ce4+ is bonded in a 8-coordinate geometry to four O2- and four equivalent F1- atoms. There are a spread of Ce–O bond distances ranging from 2.24–2.55 Å. There are two shorter (2.31 Å) and two longer (2.32 Å) Ce–F bond lengths. As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.71 Å) and three longer (1.72 Å) As–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ce4+ and one As5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Ce4+ and one As5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ce4+ and one As5+ atom. F1- is bonded in a distorted bent 120 degrees geometry to two equivalent Ce4+ atoms.
