Materials Data on ZrS2O13 by Materials Project

Abstract

ZrS2O13 is High Pressure (4-7GPa) Tellurium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one ZrS2O13 cluster. Zr is bonded to seven O atoms to form distorted ZrO7 pentagonal bipyramids that share corners with two equivalent SO4 tetrahedra and an edgeedge with one SO4 tetrahedra. There are a spread of Zr–O bond distances ranging from 2.01–2.42 Å. There are two inequivalent S sites. In the first S site, S is bonded to four O atoms to form SO4 tetrahedra that share an edgeedge with one ZrO7 pentagonal bipyramid. There are a spread of S–O bond distances ranging from 1.45–1.55 Å. In the second S site, S is bonded to four O atoms to form SO4 tetrahedra that share corners with two equivalent ZrO7 pentagonal bipyramids. There are a spread of S–O bond distances ranging from 1.46–1.52 Å. There are thirteen inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one S atom. In the second O site, O is bonded in a single-bond geometry to one S atom. In the third O site, O is bonded in a bent 150 degrees geometry to one Zr and one S atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Zr and one S atom. In the fifth O site, O is bonded in a single-bond geometry to one Zr atom. In the sixth O site, O is bonded in a distorted L-shaped geometry to one Zr and one S atom. In the seventh O site, O is bonded in a single-bond geometry to one S atom. In the eighth O site, O is bonded in a water-like geometry to one Zr and one S atom. In the ninth O site, O is bonded in a single-bond geometry to one S atom. In the tenth O site, O is bonded in a bent 120 degrees geometry to two O atoms. There is one shorter (1.25 Å) and one longer (1.33 Å) O–O bond length. In the eleventh O site, O is bonded in a single-bond geometry to one Zr atom. In the twelfth O site, O is bonded in a bent 120 degrees geometry to one Zr and one O atom. In the thirteenth O site, O is bonded in a single-bond geometry to one O atom.
