Title: Materials Data on Nd6Nb5S16 by Materials Project

Abstract

Nd6Nb5S16 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Nd–S bond distances ranging from 2.85–3.14 Å. In the second Nd3+ site, Nd3+ is bonded to seven S2- atoms to form distorted NdS7 pentagonal bipyramids that share corners with three equivalent NdS7 pentagonal bipyramids, corners with four NbS6 pentagonal pyramids, edges with two equivalent NdS7 pentagonal bipyramids, and an edgeedge with one NbS6 pentagonal pyramid. There are a spread of Nd–S bond distances ranging from 2.87–3.00 Å. In the third Nd3+ site, Nd3+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Nd–S bond distances ranging from 2.87–2.99 Å. In the fourth Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Nd–S bond distances ranging from 2.84–3.21 Å. There are six inequivalent Nb+2.80+ sites.

In the fourth S2- site, S2- is bonded to one Nd3+ and three Nb+2.80+ atoms to form distorted SNdNb3 trigonal pyramids that share corners with five SNd5 trigonal bipyramids and a faceface with one SNdNb3 trigonal pyramid. In the fifth S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to one Nd3+ and three Nb+2.80+ atoms. In the sixth S2- site, S2- is bonded to five Nd3+ atoms to form distorted SNd5 trigonal bipyramids that share corners with four SNd5 trigonal bipyramids, corners with three equivalent SNdNb3 trigonal pyramids, and edges with eight SNd5 trigonal bipyramids.
