Abstract

Ta4Te9OI4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Ta+4.50+ sites. In the first Ta+4.50+ site, Ta+4.50+ is bonded in a 1-coordinate geometry to five Te+1.33-, one O2-, and one I1- atom. There are a spread of Ta–Te bond distances ranging from 2.83–2.92 Å. The Ta–O bond length is 2.18 Å. The Ta–I bond length is 2.83 Å. In the second Ta+4.50+ site, Ta+4.50+ is bonded in a distorted single-bond geometry to four Te+1.33-, one O2-, and one I1- atom. There are two shorter (2.80 Å) and two longer (2.94 Å) Ta–Te bond lengths. The Ta–O bond length is 1.99 Å. The Ta–I bond length is 2.82 Å. There are five inequivalent Te+1.33- sites. In the first Te+1.33- site, Te+1.33- is bonded in a 3-coordinate geometry to two Ta+4.50+, one Te+1.33-, and one I1- atom. The Te–Te bond length is 2.75 Å. The Te–I bond length is 3.58 Å. In the second Te+1.33- site, Te+1.33- is bonded in a 6-coordinate geometry to two Ta+4.50+, one Te+1.33-, and three I1- atoms. The Te–Te bond length is 2.75 Å.
