Materials Data on Pr2SiTeO4 by Materials Project
Abstract
Pr2SiTeO4 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded in a 6-coordinate geometry to four equivalent Te2- and six O2- atoms. There are two shorter (3.39 Å) and two longer (3.71 Å) Pr–Te bond lengths. There are two shorter (2.55 Å) and four longer (2.56 Å) Pr–O bond lengths. In the second Pr3+ site, Pr3+ is bonded in a 6-coordinate geometry to three equivalent Te2- and six O2- atoms. There are a spread of Pr–Te bond distances ranging from 3.21–3.41 Å. There are a spread of Pr–O bond distances ranging from 2.50–2.64 Å. Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.65 Å) and two longer (1.67 Å) Si–O bond length. Te2- is bonded in a 1-coordinate geometry to seven Pr3+ and ten O2- atoms. There are a spread of Te–O bond distances ranging from 3.36–3.74 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Pr3+, one Si4+, and three equivalent Te2- atoms. In the second O2- site, O2- is bonded in amore »
