Materials Data on Zr3S4 by Materials Project

Abstract

Zr3S4 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are two inequivalent Zr+2.67+ sites. In the first Zr+2.67+ site, Zr+2.67+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing ZrS6 octahedra. The corner-sharing octahedra tilt angles range from 2–5°. There are two shorter (2.56 Å) and four longer (2.61 Å) Zr–S bond lengths. In the second Zr+2.67+ site, Zr+2.67+ is bonded to six S2- atoms to form edge-sharing ZrS6 octahedra. There are four shorter (2.63 Å) and two longer (2.67 Å) Zr–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to five Zr+2.67+ atoms to form a mixture of edge and corner-sharing SZr5 square pyramids. In the second S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Zr+2.67+ atoms.
