Zn(CoS2)2 crystallizes in the orthorhombic Imma space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form CoS6 octahedra that share edges with two equivalent Co(1)S6 octahedra, edges with four equivalent Co(2)S6 octahedra, and edges with four equivalent Zn(1)S6 octahedra. In the second Co site, Co(2) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form CoS6 octahedra that share corners with six equivalent Zn(1)S6 octahedra, edges with two equivalent Co(2)S6 octahedra, edges with two equivalent Zn(1)S6 octahedra, and edges with four equivalent Co(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 10-12°. Zn(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form ZnS6 octahedra that share corners with six equivalent Co(2)S6 octahedra, edges with two equivalent Co(2)S6 octahedra, edges with two equivalent Zn(1)S6 octahedra, and edges with four equivalent Co(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 10-12°. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Co(2), two equivalent Co(1), and one Zn(1) atom. In the second S site, S(2) is bonded to one Co(1), two equivalent Co(2), and two equivalent Zn(1) atoms to form a mixture of edge and corner-sharing SZn2Co3 square pyramids.
