The material structure described by SiI4 is Silicon tetrafluoride-like structured and crystallizes in the cubic Pa-3 space group. The structure is zero-dimensional and consists of eight silicon tetraiodide molecules. Si(1) is bonded in a tetrahedral geometry to four equivalent I(1,2) atoms. I(1,2) is bonded in a single-bond geometry to one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
