HfCrAgS4 is Spinel-derived structured and crystallizes in the orthorhombic I2_12_12_1 space group. Hf(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form HfS6 octahedra that share corners with six equivalent Ag(1)S4 tetrahedra, edges with two equivalent Hf(1)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. Cr(1) is bonded to two equivalent S(2) and four equivalent S(1) 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 Hf(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 Hf(1)S6 octahedra and corners with six equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 54-69°. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Hf(1), two equivalent Cr(1), and one Ag(1) atom to form a mixture of distorted edge and corner-sharing SHfCr2Ag trigonal pyramids. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Hf(1), one Cr(1), and one Ag(1) atom.
