Materials Data on EuTlO2 by Materials Project
EuTlO2 is Caswellsilverite structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Eu3+ is bonded to six equivalent O2- atoms to form edge-sharing EuO6 octahedra. All Eu–O bond lengths are 2.36 Å. Tl1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are two shorter (2.95 Å) and four longer (2.96 Å) Tl–O bond lengths. O2- is bonded to three equivalent Eu3+ and three equivalent Tl1+ atoms to form a mixture of distorted edge and corner-sharing OEu3Tl3 octahedra. The corner-sharing octahedral tilt angles are 0°.
