Materials Data on Ho6Mn(GeS7)2 by Materials Project

Ho6Mn(GeS7)2 crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ho–S bond distances ranging from 2.71–3.26 Å. In the second Ho3+ site, Ho3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ho–S bond distances ranging from 2.72–3.35 Å. Mn2+ is bonded in an octahedral geometry to six S2- atoms. There are three shorter (2.53 Å) and three longer (2.59 Å) Mn–S bond lengths. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded in a tetrahedral geometry to four S2- atoms. There are one shorter (2.21 Å) and three longer (2.24 Å) Ge–S bond lengths. In the second Ge4+ site, Ge4+ is bonded in a tetrahedral geometry to four S2- atoms. There are one shorter (2.20 Å) and three longer (2.24 Å) Ge–S bond lengths. There are six inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to three Ho3+ and one Ge4+ atom. In the second S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to three Ho3+ and one Ge4+ atom. In the third S2- site, S2- is bonded in a tetrahedral geometry to three equivalent Ho3+ and one Ge4+ atom. In the fourth S2- site, S2- is bonded in a tetrahedral geometry to three equivalent Ho3+ and one Ge4+ atom. In the fifth S2- site, S2- is bonded in a 4-coordinate geometry to four Ho3+ and one Mn2+ atom. In the sixth S2- site, S2- is bonded in a 5-coordinate geometry to four Ho3+ and one Mn2+ atom.
