Materials Data on CsTcO4 by Materials Project

Abstract

CsTcO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 3.20–3.36 Å. Tc7+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.74 Å) and one longer (1.75 Å) Tc–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one Tc7+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Tc7+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Cs1+ and one Tc7+ atom.
