Materials Data on K3Nb6SBr17 by Materials Project
Abstract
K3Nb6SBr17 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 10-coordinate geometry to ten Br1- atoms. There are a spread of K–Br bond distances ranging from 3.31–4.00 Å. In the second K1+ site, K1+ is bonded in a 10-coordinate geometry to ten Br1- atoms. There are a spread of K–Br bond distances ranging from 3.47–3.93 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 face, edge, and corner-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 2.62–2.84 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 face, edge, and corner-sharing NbSBr5 octahedra. The corner-sharing octahedra tilt angles range from 42–44°. 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 five Br1-more »
