Materials Data on KTlO by Materials Project
KTlO is trigonal omega-derived structured and crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two KTlO sheets oriented in the (1, 0, 0) direction. K1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. There are two shorter (2.70 Å) and one longer (2.76 Å) K–O bond lengths. Tl1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. There are one shorter (2.38 Å) and two longer (2.48 Å) Tl–O bond lengths. O2- is bonded to three equivalent K1+ and three equivalent Tl1+ atoms to form edge-sharing OK3Tl3 octahedra.
