Materials Data on BaZrSe3 by Materials Project

Abstract

BaZrSe3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine Se2- atoms. There are a spread of Ba–Se bond distances ranging from 3.33–3.90 Å. Zr4+ is bonded to six Se2- atoms to form edge-sharing ZrSe6 octahedra. There are a spread of Zr–Se bond distances ranging from 2.60–2.80 Å. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to three equivalent Ba2+ and two equivalent Zr4+ atoms. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to two equivalent Ba2+ and three equivalent Zr4+ atoms. In the third Se2- site, Se2- is bonded in a 5-coordinate geometry to four equivalent Ba2+ and one Zr4+ atom.
