Materials Data on In3Cu3O8 by Materials Project
Cu3In3O8 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Cu+2.33+ sites. In the first Cu+2.33+ site, Cu+2.33+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.89 Å) and two longer (1.90 Å) Cu–O bond length. In the second Cu+2.33+ site, Cu+2.33+ is bonded in a see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.91–1.94 Å. In the third Cu+2.33+ site, Cu+2.33+ is bonded in a see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.91–1.94 Å. In the fourth Cu+2.33+ site, Cu+2.33+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.89 Å) and two longer (1.90 Å) Cu–O bond length. There are four inequivalent In3+ sites. In the first In3+ site, In3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of In–O bond distances ranging from 2.22–2.56 Å. In the second In3+ site, In3+ is bonded in an octahedral geometry to six O2- atoms. There are two shorter (2.21 Å) and four longer (2.23 Å) In–O bond lengths. In the third In3+ site, In3+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of In–O bond distances ranging from 2.21–2.24 Å. In the fourth In3+ site, In3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of In–O bond distances ranging from 2.22–2.56 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Cu+2.33+ and one In3+ atom. In the second O2- site, O2- is bonded to one Cu+2.33+ and three In3+ atoms to form a mixture of distorted edge and corner-sharing OIn3Cu tetrahedra. In the third O2- site, O2- is bonded to one Cu+2.33+ and three In3+ atoms to form a mixture of distorted edge and corner-sharing OIn3Cu tetrahedra. In the fourth O2- site, O2- is bonded to one Cu+2.33+ and three In3+ atoms to form a mixture of edge and corner-sharing OIn3Cu tetrahedra. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to three Cu+2.33+ and one In3+ atom. In the sixth O2- site, O2- is bonded to one Cu+2.33+ and three In3+ atoms to form a mixture of distorted edge and corner-sharing OIn3Cu tetrahedra. In the seventh O2- site, O2- is bonded to one Cu+2.33+ and three In3+ atoms to form a mixture of edge and corner-sharing OIn3Cu tetrahedra. In the eighth O2- site, O2- is bonded to one Cu+2.33+ and three In3+ atoms to form a mixture of distorted edge and corner-sharing OIn3Cu tetrahedra.
