Nd3AgSiS7 crystallizes in the hexagonal P6_3 space group. Nd(1) is bonded in a 8-coordinate geometry to one S(1), three equivalent S(2), and four equivalent S(3) atoms. Ag(1) is bonded in a trigonal planar geometry to three equivalent S(3) atoms. Si(1) is bonded in a tetrahedral geometry to one S(1) and three equivalent S(2) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a distorted tetrahedral geometry to three equivalent Nd(1) and one Si(1) atom. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Nd(1) and one Si(1) atom. In the third S site, S(3) is bonded in a 5-coordinate geometry to four equivalent Nd(1) and one Ag(1) atom.
