The crystal structure described by Zr5S8 crystallizes in the cubic F-43m space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form ZrS6 octahedra that share corners with three equivalent Zr(2)S4 tetrahedra and edges with six equivalent Zr(1)S6 octahedra. In the second Zr site, Zr(2) is bonded to four equivalent S(1) atoms to form corner-sharing ZrS4 tetrahedra. The corner-sharing octahedral tilt angles are 63°. There are two inequivalent S sites. In the first S site, S(2) is bonded in a 3-coordinate geometry to three equivalent Zr(1) atoms. In the second S site, S(1) is bonded to one Zr(2) and three equivalent Zr(1) atoms to form a mixture of corner and edge-sharing SZr4 tetrahedra. is represented by the CIF file [CIF]
