Title: Materials Data on Nd6Si4S17 by Materials Project

Abstract

Nd6Si4S17 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are six inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded to seven S2- atoms to form distorted NdS7 pentagonal bipyramids that share corners with two SiS4 tetrahedra and edges with two SiS4 tetrahedra. There are a spread of Nd–S bond distances ranging from 2.83–3.00 Å. In the second 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 2.87–3.24 Å. In the third Nd3+ site, Nd3+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Nd–S bond distances ranging from 2.88–3.27 Å. In the fourth Nd3+ site, Nd3+ is bonded in a 9-coordinate geometry to eight S2- atoms.

In the eighth S2- site, S2- is bonded in a 4-coordinate geometry to three Nd3+ and one Si4+ atom. In the ninth S2- site, S2- is bonded in a 3-coordinate geometry to two Nd3+ and one Si4+ atom. In the tenth S2- site, S2- is bonded in a distorted T-shaped geometry to two Nd3+ and one Si4+ atom. In the eleventh S2- site, S2- is bonded to three Nd3+ and one Si4+ atom to form distorted SNd3Si trigonal pyramids that share corners with two SNd3Si trigonal pyramids and an edgeedge with one SNd4 tetrahedra. In the twelfth S2- site, S2- is bonded in a 1-coordinate geometry to four Nd3+ and one Si4+ atom.

In the fourteenth S2- site, S2- is bonded in a 4-coordinate geometry to three Nd3+ and one Si4+ atom. In the fifteenth S2- site, S2- is bonded to four Nd3+ atoms to form a mixture of distorted edge and corner-sharing SNd4 tetrahedra. In the sixteenth S2- site, S2- is bonded in a 4-coordinate geometry to three Nd3+ and one Si4+ atom. In the seventeenth S2- site, S2- is bonded in a distorted T-shaped geometry to two Nd3+ and one Si4+ atom.« less
