Materials Data on TeOsCl2 by Materials Project

Abstract

OsTeCl2 crystallizes in the cubic F-43m space group. The structure is three-dimensional. Os4+ is bonded in a body-centered cubic geometry to four equivalent Te2- and four equivalent Cl1- atoms. All Os–Te bond lengths are 2.89 Å. All Os–Cl bond lengths are 2.89 Å. Te2- is bonded in a 4-coordinate geometry to four equivalent Os4+ and ten Cl1- atoms. There are four shorter (2.89 Å) and six longer (3.33 Å) Te–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded to four equivalent Te2- atoms to form distorted ClTe4 tetrahedra that share corners with twenty-four ClTe4 tetrahedra and faces with four equivalent ClTe6Os4 tetrahedra. In the second Cl1- site, Cl1- is bonded to four equivalent Os4+ and six equivalent Te2- atoms to form a mixture of distorted face and corner-sharing ClTe6Os4 tetrahedra.
