Title: Materials Data on Rb3Nb2AsSe11 by Materials Project

Abstract

Rb3Nb2AsSe11 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 1-coordinate geometry to ten Se+1.45- atoms. There are a spread of Rb–Se bond distances ranging from 3.56–4.16 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight Se+1.45- atoms. There are a spread of Rb–Se bond distances ranging from 3.43–4.09 Å. In the third Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine Se+1.45- atoms. There are a spread of Rb–Se bond distances ranging from 3.51–3.76 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to seven Se+1.45- atoms to form distorted face-sharing NbSe7 pentagonal bipyramids. There are a spread of Nb–Se bond distances ranging from 2.38–2.91 Å. In the second Nb5+ site, Nb5+ is bonded to seven Se+1.45- atoms to form distorted face-sharing NbSe7 pentagonal bipyramids. There are a spread of Nb–Se bond distances ranging from 2.37–2.97 Å. As3+ is bonded in a distorted trigonal non-coplanar geometry to three Se+1.45- atoms. There are a spread of As–Se bond distances ranging from 2.41–2.47 Å. There are eleven inequivalent Se+1.45-more » sites. In the first Se+1.45- site, Se+1.45- is bonded in a 1-coordinate geometry to four Rb1+ and one Nb5+ atom. In the second Se+1.45- site, Se+1.45- is bonded in a 1-coordinate geometry to three Rb1+ and one Nb5+ atom. In the third Se+1.45- site, Se+1.45- is bonded in a distorted single-bond geometry to four Rb1+ and one Nb5+ atom. In the fourth Se+1.45- site, Se+1.45- is bonded in a distorted L-shaped geometry to three Rb1+, one Nb5+, and one As3+ atom. In the fifth Se+1.45- site, Se+1.45- is bonded in a 2-coordinate geometry to two Rb1+, two Nb5+, and one Se+1.45- atom. The Se–Se bond length is 2.39 Å. In the sixth Se+1.45- site, Se+1.45- is bonded in a 1-coordinate geometry to two Rb1+, one Nb5+, and one Se+1.45- atom. In the seventh Se+1.45- site, Se+1.45- is bonded in a 2-coordinate geometry to two Rb1+, one Nb5+, and one Se+1.45- atom. The Se–Se bond length is 2.39 Å. In the eighth Se+1.45- site, Se+1.45- is bonded in a 2-coordinate geometry to two Rb1+, two Nb5+, and one Se+1.45- atom. In the ninth Se+1.45- site, Se+1.45- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Nb5+, and one As3+ atom. In the tenth Se+1.45- site, Se+1.45- is bonded in a 2-coordinate geometry to three Rb1+ and two Nb5+ atoms. In the eleventh Se+1.45- site, Se+1.45- is bonded in an L-shaped geometry to one Nb5+ and one As3+ atom.« less
