Ca(CrS2)2 crystallizes in the orthorhombic Imma space group. Ca(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form CaS6 octahedra that share corners with six equivalent Cr(2)S6 octahedra, edges with two equivalent Ca(1)S6 octahedra, edges with two equivalent Cr(2)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 9-10°. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form CrS6 octahedra that share edges with two equivalent Cr(1)S6 octahedra, edges with four equivalent Ca(1)S6 octahedra, and edges with four equivalent Cr(2)S6 octahedra. In the second Cr site, Cr(2) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form CrS6 octahedra that share corners with six equivalent Ca(1)S6 octahedra, edges with two equivalent Ca(1)S6 octahedra, edges with two equivalent Cr(2)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 9-10°. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Ca(1), one Cr(2), and two equivalent Cr(1) atoms. In the second S site, S(2) is bonded to two equivalent Ca(1), one Cr(1), and two equivalent Cr(2) atoms to form a mixture of corner and edge-sharing SCa2Cr3 square pyramids.
