Fe4PdNi4S8 crystallizes in the cubic F-43m space group. Fe(1) is bonded to one S(2) and three equivalent S(1) atoms to form FeS4 tetrahedra that share corners with three equivalent Pd(1)S6 octahedra, corners with six equivalent Fe(1)S4 tetrahedra, and edges with three equivalent Ni(1)S4 tetrahedra. The corner-sharing octahedral tilt angles are 55°. Pd(1) is bonded to six equivalent S(1) atoms to form PdS6 octahedra that share corners with twelve equivalent Fe(1)S4 tetrahedra and corners with twelve equivalent Ni(1)S4 tetrahedra. Ni(1) is bonded to one S(3) and three equivalent S(1) atoms to form distorted NiS4 tetrahedra that share corners with three equivalent Pd(1)S6 octahedra, corners with six equivalent Ni(1)S4 tetrahedra, and edges with three equivalent Fe(1)S4 tetrahedra. The corner-sharing octahedral tilt angles are 55°. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Fe(1), one Pd(1), and two equivalent Ni(1) atoms. In the second S site, S(2) is bonded in a tetrahedral geometry to four equivalent Fe(1) atoms. In the third S site, S(3) is bonded in a tetrahedral geometry to four equivalent Ni(1) atoms.
