The crystal structure described by SiH4 is Silicon tetrafluoride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four 5j076063r1 molecules. Si(1) is bonded in a tetrahedral geometry to one H(1); one H(4); and two equivalent H(2,3) atoms. There are three inequivalent H sites. In the first H site, H(2,3) is bonded in a single-bond geometry to one Si(1) atom. In the second H site, H(1) is bonded in a single-bond geometry to one Si(1) atom. In the third H site, H(4) is bonded in a single-bond geometry to one Si(1) atom. is represented by the CIF file [CIF]
