The crystal structure described by Cr5AgS8 crystallizes in the monoclinic P2_1/m space group. There are four inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one S(2), one S(5), two equivalent S(3), and two equivalent S(4) atoms to form a mixture of corner and edge-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 48-50°. In the second Cr site, Cr(2) is bonded to two equivalent S(2), two equivalent S(4), and two equivalent S(6) atoms to form a mixture of corner, face, and edge-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 47-50°. In the third Cr site, Cr(3) is bonded to one S(1), one S(2), one S(3), one S(4), one S(5), and one S(6) atom to form a mixture of corner, face, and edge-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 48°. In the fourth Cr site, Cr(4) is bonded to one S(1), one S(6), two equivalent S(3), and two equivalent S(4) atoms to form a mixture of corner and edge-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 47-49°. Ag(1) is bonded in a 4-coordinate geometry to one S(1), one S(5), and two equivalent S(3) atoms. There are six inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Cr(4), two equivalent Cr(3), and one Ag(1) atom. In the second S site, S(2) is bonded to one Cr(1), two equivalent Cr(2), and two equivalent Cr(3) atoms to form distorted SCr5 square pyramids that share corners with two equivalent S(2)Cr5 square pyramids, edges with three equivalent S(6)Cr5 square pyramids, and edges with two equivalent S(3)Cr3Ag trigonal pyramids. In the third S site, S(3) is bonded to one Cr(1), one Cr(3), one Cr(4), and one Ag(1) atom to form distorted SCr3Ag trigonal pyramids that share  a cornercorner with one S(3)Cr3Ag trigonal pyramid,  an edgeedge with one S(2)Cr5 square pyramid,  an edgeedge with one S(6)Cr5 square pyramid, and  an edgeedge with one S(3)Cr3Ag trigonal pyramid. In the fourth S site, S(4) is bonded in a rectangular see-saw-like geometry to one Cr(1), one Cr(2), one Cr(3), and one Cr(4) atom. In the fifth S site, S(5) is bonded in a rectangular see-saw-like geometry to one Cr(1), two equivalent Cr(3), and one Ag(1) atom. In the sixth S site, S(6) is bonded to one Cr(4), two equivalent Cr(2), and two equivalent Cr(3) atoms to form distorted SCr5 square pyramids that share corners with two equivalent S(6)Cr5 square pyramids, edges with three equivalent S(2)Cr5 square pyramids, and edges with two equivalent S(3)Cr3Ag trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
