Materials Data on Ce2Te3 by Materials Project
Ce2Te3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded to seven Te2- atoms to form a mixture of distorted edge and corner-sharing CeTe7 pentagonal bipyramids. There are a spread of Ce–Te bond distances ranging from 3.18–3.25 Å. In the second Ce3+ site, Ce3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of Ce–Te bond distances ranging from 3.25–3.69 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to five Ce3+ atoms to form a mixture of distorted edge and corner-sharing TeCe5 trigonal bipyramids. In the second Te2- site, Te2- is bonded to five Ce3+ atoms to form a mixture of distorted edge and corner-sharing TeCe5 square pyramids. In the third Te2- site, Te2- is bonded in a 5-coordinate geometry to five Ce3+ atoms.
