Cr(InS2)2 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Cr(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form CrS6 octahedra that share corners with six equivalent In(1)S4 tetrahedra, edges with two equivalent Cr(1)S6 octahedra, and edges with four equivalent In(2)S6 octahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form InS4 tetrahedra that share corners with six equivalent Cr(1)S6 octahedra and corners with six equivalent In(2)S6 octahedra. The corner-sharing octahedral tilt angles range from 52-67°. In the second In site, In(2) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form InS6 octahedra that share corners with six equivalent In(1)S4 tetrahedra, edges with two equivalent In(2)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Cr(1), one In(1), and two equivalent In(2) atoms. In the second S site, S(2) is bonded to two equivalent Cr(1), one In(1), and one In(2) atom to form a mixture of distorted edge and corner-sharing SCr2In2 trigonal pyramids.
