Materials Data on Tl2(SbO3)3 by Materials Project
Tl2(SbO3)3 crystallizes in the cubic Pn-3 space group. The structure is three-dimensional. Tl is bonded in a 6-coordinate geometry to six O atoms. There are three shorter (2.70 Å) and three longer (2.86 Å) Tl–O bond lengths. Sb is bonded to six O atoms to form a mixture of edge and corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Sb–O bond distances ranging from 1.99–2.04 Å. There are two inequivalent O sites. In the first O site, O is bonded in a water-like geometry to two equivalent Tl and two equivalent Sb atoms. In the second O site, O is bonded in a distorted trigonal planar geometry to one Tl and two equivalent Sb atoms.
