Title: Materials Data on Dy3Si3O10F by Materials Project

Abstract

Dy3Si3O10F crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 7-coordinate geometry to six O2- and one F1- atom. There are a spread of Dy–O bond distances ranging from 2.30–2.58 Å. The Dy–F bond length is 2.26 Å. In the second Dy3+ site, Dy3+ is bonded to six O2- and one F1- atom to form DyO6F pentagonal bipyramids that share corners with six SiO4 tetrahedra. There are a spread of Dy–O bond distances ranging from 2.24–2.48 Å. The Dy–F bond length is 2.39 Å. In the third Dy3+ site, Dy3+ is bonded in a 6-coordinate geometry to five O2- and one F1- atom. There are a spread of Dy–O bond distances ranging from 2.26–2.41 Å. The Dy–F bond length is 2.30 Å. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent DyO6F pentagonal bipyramids and a cornercorner with one SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.64–1.68 Å. In the second Si4+ site, Si4+ is bonded to fourmore » O2- atoms to form SiO4 tetrahedra that share corners with two equivalent DyO6F pentagonal bipyramids and corners with two SiO4 tetrahedra. There is two shorter (1.63 Å) and two longer (1.66 Å) Si–O bond length. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent DyO6F pentagonal bipyramids and a cornercorner with one SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.63–1.67 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Dy3+ and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Si4+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Dy3+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two Dy3+ and one Si4+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Dy3+ and one Si4+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Si4+ atoms. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to three Dy3+ and one Si4+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Dy3+ and one Si4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Dy3+ and one Si4+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Dy3+ and one Si4+ atom. F1- is bonded in a 3-coordinate geometry to three Dy3+ atoms.« less
