Cr2AgS4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one S(1), two equivalent S(4), and three equivalent S(2) atoms to form a mixture of edge and corner-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 48-55°. In the second Cr site, Cr(2) is bonded to one S(4), two equivalent S(1), and three equivalent S(3) atoms to form a mixture of edge and corner-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 48-55°. Ag(1) is bonded in a 7-coordinate geometry to one S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to one Cr(1), two equivalent Cr(2), and one Ag(1) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent Cr(1) and two equivalent Ag(1) atoms. In the third S site, S(3) is bonded to three equivalent Cr(2) and two equivalent Ag(1) atoms to form distorted edge-sharing SCr3Ag2 trigonal bipyramids. In the fourth S site, S(4) is bonded in a 5-coordinate geometry to one Cr(2), two equivalent Cr(1), and two equivalent Ag(1) atoms.
