Title: Materials Data on CaZrSi6O17 by Materials Project

Abstract

CaZrSi6O17 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Ca is bonded to seven O atoms to form distorted CaO7 hexagonal pyramids that share corners with two SiO4 tetrahedra, edges with two equivalent ZrO6 octahedra, and edges with two SiO4 tetrahedra. There are a spread of Ca–O bond distances ranging from 2.39–2.51 Å. Zr is bonded to six O atoms to form ZrO6 octahedra that share corners with six SiO4 tetrahedra and edges with two equivalent CaO7 hexagonal pyramids. There are a spread of Zr–O bond distances ranging from 2.03–2.22 Å. There are six inequivalent Si sites. In the first Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one ZrO6 octahedra, corners with three SiO4 tetrahedra, and an edgeedge with one CaO7 hexagonal pyramid.
