Materials Data on NbAg7S6 by Materials Project
Abstract
Ag7NbS6 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Nb5+ is bonded to four S2- atoms to form NbS4 tetrahedra that share corners with two equivalent AgS4 tetrahedra and an edgeedge with one AgS4 tetrahedra. There are a spread of Nb–S bond distances ranging from 2.27–2.37 Å. There are seven inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three S2- atoms. There are a spread of Ag–S bond distances ranging from 2.52–2.66 Å. In the second Ag1+ site, Ag1+ is bonded to four S2- atoms to form distorted AgS4 tetrahedra that share corners with three equivalent AgS4 tetrahedra and an edgeedge with one NbS4 tetrahedra. There are a spread of Ag–S bond distances ranging from 2.56–2.83 Å. In the third Ag1+ site, Ag1+ is bonded in a 3-coordinate geometry to three S2- atoms. There are a spread of Ag–S bond distances ranging from 2.49–2.62 Å. In the fourth Ag1+ site, Ag1+ is bonded to four S2- atoms to form distorted AgS4 tetrahedra that share corners with two equivalent NbS4 tetrahedra and corners with three equivalent AgS4 tetrahedra. There are a spread of Ag–S bond distances ranging from 2.62–2.68 Å.more »
