Title: Materials Data on Rb3Nb6SBr17 by Materials Project

Abstract

Rb3Nb6SBr17 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of Rb–Br bond distances ranging from 3.44–3.96 Å. In the second Rb1+ site, Rb1+ is bonded in a distorted q6 geometry to ten Br1- atoms. There are a spread of Rb–Br bond distances ranging from 3.60–3.94 Å. There are three inequivalent Nb+2.67+ sites. In the first Nb+2.67+ site, Nb+2.67+ is bonded to one S2- and five Br1- atoms to form a mixture of edge, corner, and face-sharing NbSBr5 octahedra. The corner-sharing octahedra tilt angles range from 41–43°. The Nb–S bond length is 2.39 Å. There are a spread of Nb–Br bond distances ranging from 2.61–2.73 Å. In the second Nb+2.67+ site, Nb+2.67+ is bonded to one S2- and five Br1- atoms to form a mixture of edge, corner, and face-sharing NbSBr5 octahedra. The corner-sharing octahedra tilt angles range from 41–44°. The Nb–S bond length is 2.38 Å. There are a spread of Nb–Br bond distances ranging from 2.60–2.76 Å. In the third Nb+2.67+ site, Nb+2.67+ is bonded to one S2- and fivemore » Br1- atoms to form a mixture of edge, corner, and face-sharing NbSBr5 octahedra. The corner-sharing octahedra tilt angles range from 40–50°. The Nb–S bond length is 2.38 Å. There are a spread of Nb–Br bond distances ranging from 2.62–2.86 Å. S2- is bonded in a distorted pentagonal pyramidal geometry to six Nb+2.67+ atoms. There are nine inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 3-coordinate geometry to one Rb1+ and two Nb+2.67+ atoms. In the second Br1- site, Br1- is bonded in a 4-coordinate geometry to three Rb1+ and one Nb+2.67+ atom. In the third Br1- site, Br1- is bonded in a bent 120 degrees geometry to two equivalent Nb+2.67+ atoms. In the fourth Br1- site, Br1- is bonded in a 4-coordinate geometry to two equivalent Rb1+ and two Nb+2.67+ atoms. In the fifth Br1- site, Br1- is bonded in a 3-coordinate geometry to one Rb1+ and two Nb+2.67+ atoms. In the sixth Br1- site, Br1- is bonded in a 2-coordinate geometry to two equivalent Rb1+ and two equivalent Nb+2.67+ atoms. In the seventh Br1- site, Br1- is bonded in a 3-coordinate geometry to two equivalent Rb1+ and one Nb+2.67+ atom. In the eighth Br1- site, Br1- is bonded in a 2-coordinate geometry to one Rb1+ and two Nb+2.67+ atoms. In the ninth Br1- site, Br1- is bonded in a 2-coordinate geometry to one Rb1+ and two Nb+2.67+ atoms.« less
