Materials Data on InCuO2 by Materials Project
CuInO2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cu1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.85 Å. In3+ is bonded to six equivalent O2- atoms to form edge-sharing InO6 octahedra. All In–O bond lengths are 2.21 Å. O2- is bonded to one Cu1+ and three equivalent In3+ atoms to form a mixture of distorted edge and corner-sharing OIn3Cu tetrahedra.
