SiS4 is Indium-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two tetrathiosilicic acid molecules. Si(1) is bonded in a tetrahedral geometry to one S(2), one S(3), and two equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(3) is bonded in a distorted single-bond geometry to one Si(1) atom. In the second S site, S(1) is bonded in a distorted single-bond geometry to one Si(1) atom. In the third S site, S(2) is bonded in a distorted single-bond geometry to one Si(1) atom.
