Title: Materials Data on Ca2Gd3Si3O13 by Materials Project

Abstract

Ca2Gd3Si3O13 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Ca is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Ca–O bond distances ranging from 2.40–2.88 Å. Gd is bonded to seven O atoms to form distorted GdO7 pentagonal bipyramids that share corners with six equivalent GdO7 pentagonal bipyramids, corners with four equivalent SiO4 tetrahedra, and an edgeedge with one SiO4 tetrahedra. There are a spread of Gd–O bond distances ranging from 2.33–2.60 Å. Si is bonded to four O atoms to form SiO4 tetrahedra that share corners with four equivalent GdO7 pentagonal bipyramids and an edgeedge with one GdO7 pentagonal bipyramid. There are a spread of Si–O bond distances ranging from 1.62–1.65 Å. There are four inequivalent O sites. In the first O site, O is bonded in a 4-coordinate geometry to two equivalent Ca, one Gd, and one Si atom. In the second O site, O is bonded in a trigonal planar geometry to three equivalent Gd atoms. In the third O site, O is bonded in a 4-coordinate geometry to two equivalent Ca, one Gd, and one Si atom. In the fourth O site, O is bonded in amore » 1-coordinate geometry to one Ca, two equivalent Gd, and one Si atom.« less
