The compound described by La3AgSnS7 crystallizes in the hexagonal P6_3 space group. La(1) is bonded in a 8-coordinate geometry to one S(3), three equivalent S(2), and four equivalent S(1) atoms. Ag(1) is bonded in a trigonal planar geometry to three equivalent S(1) atoms. Sn(1) is bonded in a tetrahedral geometry to one S(3) and three equivalent S(2) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to four equivalent La(1) and one Ag(1) atom. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent La(1) and one Sn(1) atom. In the third S site, S(3) is bonded in a tetrahedral geometry to three equivalent La(1) and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
