Materials Data on ErMoO5 by Materials Project

Abstract

ErMoO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Er is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Er–O bond distances ranging from 2.26–2.45 Å. Mo is bonded in a distorted tetrahedral geometry to five O atoms. There are a spread of Mo–O bond distances ranging from 1.77–2.44 Å. There are five inequivalent O sites. In the first O site, O is bonded in a 3-coordinate geometry to two equivalent Er and one Mo atom. In the second O site, O is bonded in a distorted trigonal planar geometry to two equivalent Er and one Mo atom. In the third O site, O is bonded in a distorted trigonal planar geometry to two equivalent Er and one Mo atom. In the fourth O site, O is bonded in a linear geometry to one Er and one Mo atom. In the fifth O site, O is bonded in a distorted bent 150 degrees geometry to one Er and one Mo atom.
