Materials Data on Cs2Te3 by Materials Project
Cs2Te3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are two inequivalent Cs sites. In the first Cs site, Cs is bonded in a 8-coordinate geometry to eight Te atoms. There are a spread of Cs–Te bond distances ranging from 3.90–4.20 Å. In the second Cs site, Cs is bonded in a 7-coordinate geometry to seven Te atoms. There are a spread of Cs–Te bond distances ranging from 3.89–4.04 Å. There are two inequivalent Te sites. In the first Te site, Te is bonded in a 5-coordinate geometry to three Cs and two equivalent Te atoms. Both Te–Te bond lengths are 2.83 Å. In the second Te site, Te is bonded to six Cs and one Te atom to form a mixture of distorted face, edge, and corner-sharing TeCs6Te pentagonal bipyramids.
