Title: Materials Data on Pr2Si2O7 by Materials Project

Abstract

Pr2Si2O7 crystallizes in the tetragonal P4_1 space group. The structure is three-dimensional. there are four inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pr–O bond distances ranging from 2.43–2.92 Å. In the second Pr3+ site, Pr3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pr–O bond distances ranging from 2.35–2.68 Å. In the third Pr3+ site, Pr3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pr–O bond distances ranging from 2.41–2.99 Å. In the fourth Pr3+ site, Pr3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pr–O bond distances ranging from 2.43–2.69 Å. There are four inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.69 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. In the third Si4+ site, Si4+more » is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.61–1.69 Å. In the fourth Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.68 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two Pr3+ and one Si4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two Pr3+ and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Pr3+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Pr3+ and two Si4+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Pr3+ and one Si4+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to three Pr3+ and one Si4+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to three Pr3+ and one Si4+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to two Pr3+ and one Si4+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to three Pr3+ and one Si4+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to three Pr3+ and one Si4+ atom. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to three Pr3+ and one Si4+ atom. In the twelfth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Pr3+ and one Si4+ atom. In the thirteenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Pr3+ and two Si4+ atoms. In the fourteenth O2- site, O2- is bonded in a 1-coordinate geometry to two Pr3+ and one Si4+ atom.« less
