Materials Data on TlTcO2 by Materials Project
TcTlO2 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Tc3+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent O2- atoms. There are two shorter (2.06 Å) and two longer (2.07 Å) Tc–O bond lengths. Tl1+ is bonded to six equivalent O2- atoms to form edge-sharing TlO6 octahedra. There are a spread of Tl–O bond distances ranging from 2.67–3.03 Å. O2- is bonded in a 5-coordinate geometry to two equivalent Tc3+ and three equivalent Tl1+ atoms.
