The material structure described by Si5(H2Cl)4 is Protactinium structured and crystallizes in the tetragonal I-4 space group. The structure is zero-dimensional and consists of two tetrakis(chlorosilyl)silane molecules. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a tetrahedral geometry to four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a trigonal non-coplanar geometry to one Si(1), one H(1), one H(2), and one Cl(1) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one Si(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one Si(2) atom. Cl(1) is bonded in a single-bond geometry to one Si(2) atom. is represented by the CIF card [CIF]
