Materials Data on Te2SO7 by Materials Project
Te2SO7 crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. Te4+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.92–2.95 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.47–1.51 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to two equivalent Te4+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Te4+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Te4+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to two equivalent Te4+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Te4+ atoms.
