Materials Data on Sm3CuGeS7 by Materials Project
Sm3CuGeS7 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. Sm3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Sm–S bond distances ranging from 2.80–3.25 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent S2- atoms. All Cu–S bond lengths are 2.26 Å. Ge4+ is bonded in a tetrahedral geometry to four S2- atoms. There are one shorter (2.20 Å) and three longer (2.25 Å) Ge–S bond lengths. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Sm3+ and one Ge4+ atom. In the second S2- site, S2- is bonded in a distorted tetrahedral geometry to three equivalent Sm3+ and one Ge4+ atom. In the third S2- site, S2- is bonded in a 5-coordinate geometry to four equivalent Sm3+ and one Cu1+ atom.
