Materials Data on Ag8GeS6 by Materials Project
Ag8GeS6 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are eight 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 2.55–2.65 Å. In the second Ag1+ site, Ag1+ is bonded in a distorted linear geometry to two S2- atoms. There are one shorter (2.44 Å) and one longer (2.47 Å) Ag–S bond lengths. 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 2.51–2.65 Å. In the fourth Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.59–2.90 Å. In the fifth Ag1+ site, Ag1+ is bonded in a 2-coordinate geometry to three S2- atoms. There are a spread of Ag–S bond distances ranging from 2.48–2.99 Å. In the sixth Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.60–2.95 Å. In the seventh Ag1+ site, Ag1+ is bonded to four S2- atoms to form distorted AgS4 tetrahedra that share corners with two equivalent GeS4 tetrahedra. There are a spread of Ag–S bond distances ranging from 2.65–2.73 Å. In the eighth Ag1+ site, Ag1+ is bonded in a distorted trigonal planar geometry to three S2- atoms. There are a spread of Ag–S bond distances ranging from 2.52–2.57 Å. Ge4+ is bonded to four S2- atoms to form GeS4 tetrahedra that share corners with two equivalent AgS4 tetrahedra. There are a spread of Ge–S bond distances ranging from 2.24–2.26 Å. There are six inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to six Ag1+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to five Ag1+ atoms. In the third S2- site, S2- is bonded in a distorted tetrahedral geometry to three Ag1+ and one Ge4+ atom. In the fourth S2- site, S2- is bonded in a 5-coordinate geometry to four Ag1+ and one Ge4+ atom. In the fifth S2- site, S2- is bonded in a 5-coordinate geometry to four Ag1+ and one Ge4+ atom. In the sixth S2- site, S2- is bonded in a 5-coordinate geometry to four Ag1+ and one Ge4+ atom.
