The material described by SiCl4 is Silicon tetrafluoride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four tetrachlorosilane molecules. Si(1) is bonded in a tetrahedral geometry to one Cl(1); one Cl(3); and two equivalent Cl(2,4) atoms. There are three inequivalent Cl sites. In the first Cl site, Cl(2,4) is bonded in a single-bond geometry to one Si(1) atom. In the second Cl site, Cl(1) is bonded in a single-bond geometry to one Si(1) atom. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Si(1) atom. is represented by the CIF card [CIF]
