Materials Data on CuSeO3 by Materials Project

Abstract

CuSeO3 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Cu2+ is bonded to five O2- atoms to form a mixture of distorted corner and edge-sharing CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.97–2.31 Å. Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.72–1.79 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one Se4+ atom.
