Materials Data on RbTlO by Materials Project
RbTlO is trigonal omega-derived structured and crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two RbTlO sheets oriented in the (1, 0, 0) direction. Rb1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. There are two shorter (2.85 Å) and one longer (2.90 Å) Rb–O bond lengths. Tl1+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. There are one shorter (2.37 Å) and two longer (2.49 Å) Tl–O bond lengths. O2- is bonded to three equivalent Rb1+ and three equivalent Tl1+ atoms to form edge-sharing ORb3Tl3 octahedra.
