Materials Data on TlGeO3 by Materials Project

Abstract

TlGeO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tl3+ is bonded to twelve equivalent O2- atoms to form TlO12 cuboctahedra that share corners with twelve equivalent TlO12 cuboctahedra, faces with six equivalent TlO12 cuboctahedra, and faces with eight equivalent GeO6 octahedra. All Tl–O bond lengths are 2.73 Å. Ge3+ is bonded to six equivalent O2- atoms to form GeO6 octahedra that share corners with six equivalent GeO6 octahedra and faces with eight equivalent TlO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ge–O bond lengths are 1.93 Å. O2- is bonded in a distorted linear geometry to four equivalent Tl3+ and two equivalent Ge3+ atoms.
