Materials Data on Cu4Se3O10 by Materials Project

Abstract

Cu4Se3O10 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.92–2.40 Å. In the second Cu2+ site, Cu2+ is bonded to five O2- atoms to form a mixture of edge and corner-sharing CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.94–2.32 Å. In the third Cu2+ site, Cu2+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing CuO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.97–2.30 Å. In the fourth Cu2+ site, Cu2+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.96–2.40 Å. There are three inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.73 Å) and two longer (1.76 Å) Se–O bond length. In the second Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.71–1.79 Å. In the third Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.73 Å) and one longer (1.75 Å) Se–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Cu2+ and one Se4+ atom. In the second O2- site, O2- is bonded to four Cu2+ atoms to form edge-sharing OCu4 tetrahedra. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cu2+ and one Se4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu2+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two Cu2+ and one Se4+ atom. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two Cu2+ and one Se4+ atom. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to two Cu2+ and one Se4+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one Se4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one Se4+ atom. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one Se4+ atom.
