The structure described by AgCrTiS4 is Spinel-derived structured and crystallizes in the orthorhombic I2_12_12_1 space group. Ti(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form TiS6 octahedra that share corners with six equivalent Ag(1)S4 tetrahedra, edges with two equivalent Ti(1)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. 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 Ag(1)S4 tetrahedra, edges with two equivalent Cr(1)S6 octahedra, and edges with four equivalent Ti(1)S6 octahedra. Ag(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form AgS4 tetrahedra that share corners with six equivalent Ti(1)S6 octahedra and corners with six equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 55-63°. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to two equivalent Ti(1), one Cr(1), and one Ag(1) atom. In the second S site, S(2) is bonded to one Ti(1), two equivalent Cr(1), and one Ag(1) atom to form a mixture of distorted edge and corner-sharing STiCr2Ag tetrahedra. is represented by the CIF file [CIF]
