Materials Data on ZrSiO4 by Materials Project

Abstract

ZrSiO4 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Zr4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Zr–O bond distances ranging from 2.07–2.53 Å. Si4+ is bonded to six O2- atoms to form distorted edge-sharing SiO6 octahedra. There are a spread of Si–O bond distances ranging from 1.73–1.91 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Zr4+ and two equivalent Si4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Zr4+ and one Si4+ atom.
