The structure described by RhNi2S4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Rh(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form RhS6 octahedra that share corners with six equivalent Ni(1)S4 tetrahedra, edges with two equivalent Rh(1)S6 octahedra, and edges with four equivalent Ni(2)S6 octahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form NiS4 tetrahedra that share corners with six equivalent Rh(1)S6 octahedra and corners with six equivalent Ni(2)S6 octahedra. The corner-sharing octahedral tilt angles range from 55-59°. In the second Ni site, Ni(2) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form NiS6 octahedra that share corners with six equivalent Ni(1)S4 tetrahedra, edges with two equivalent Ni(2)S6 octahedra, and edges with four equivalent Rh(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 two equivalent Rh(1), one Ni(1), and one Ni(2) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Rh(1), one Ni(1), and two equivalent Ni(2) atoms. is represented by the CIF file [CIF]
