NiCu2SiS4 crystallizes in the orthorhombic Cmmm space group. Ni(1) is bonded in a square co-planar geometry to four equivalent S(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent S(1) atoms. Si(1) is bonded in a square co-planar geometry to four equivalent S(1) atoms. S(1) is bonded to one Ni(1), two equivalent Cu(1), and one Si(1) atom to form a mixture of distorted edge and corner-sharing SCu2SiNi tetrahedra.
