Materials Data on TlCuO2 by Materials Project
CuTlO2 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 1.83 Å. Tl3+ is bonded to six equivalent O2- atoms to form edge-sharing TlO6 octahedra. All Tl–O bond lengths are 2.33 Å. O2- is bonded to one Cu1+ and three equivalent Tl3+ atoms to form a mixture of distorted edge and corner-sharing OTl3Cu tetrahedra.
