AgPS3 crystallizes in the monoclinic C2/m space group. Ag(1) is bonded to two equivalent S(1) and two equivalent S(3) atoms to form distorted AgS4 trigonal pyramids that share corners with four equivalent P(1)S4 tetrahedra and edges with two equivalent Ag(1)S4 trigonal pyramids. P(1) is bonded to one S(1), one S(3), and two equivalent S(2) atoms to form PS4 tetrahedra that share corners with four equivalent Ag(1)S4 trigonal pyramids and  an edgeedge with one P(1)S4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ag(1) and one P(1) atom. In the second S site, S(2) is bonded in an L-shaped geometry to two equivalent P(1) atoms. In the third S site, S(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ag(1) and one P(1) atom.
