MnAg4(SbS3)2 crystallizes in the monoclinic P2_1/c space group. Mn(1) is bonded to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms to form MnS6 octahedra that share corners with four equivalent Ag(2)S4 trigonal pyramids and edges with two equivalent Ag(2)S4 trigonal pyramids. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted linear geometry to one S(2) and one S(3) atom. In the second Ag site, Ag(2) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form distorted AgS4 trigonal pyramids that share corners with two equivalent Mn(1)S6 octahedra, corners with two equivalent Ag(2)S4 trigonal pyramids, and  an edgeedge with one Mn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 40-74°. Sb(1) is bonded in a 3-coordinate geometry to one S(1), one S(2), and one S(3) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded to one Mn(1), two equivalent Ag(2), and one Sb(1) atom to form distorted corner-sharing SMnAg2Sb tetrahedra. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Mn(1), one Ag(1), one Ag(2), and one Sb(1) atom. In the third S site, S(3) is bonded to one Mn(1), one Ag(1), one Ag(2), and one Sb(1) atom to form corner-sharing SMnAg2Sb tetrahedra.
