Materials Data on Na2Be2O3 by Materials Project

Abstract

Na2Be2O3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.28–2.52 Å. Be2+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of Be–O bond distances ranging from 1.50–1.58 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Na1+ and two equivalent Be2+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Na1+ and two equivalent Be2+ atoms.
