Si3CCl8 is Silicon tetrafluoride-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Si3CCl8 cluster. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded to one C(1), one Cl(6), one Cl(7), and one Cl(8) atom to form SiCCl3 tetrahedra that share  a cornercorner with one Si(3)CCl3 tetrahedra and corners with two equivalent Si(2)C2Cl2 tetrahedra. In the second Si site, Si(2) is bonded to two equivalent C(1), one Cl(1), and one Cl(2) atom to form SiC2Cl2 tetrahedra that share corners with two equivalent Si(1)CCl3 tetrahedra, corners with two equivalent Si(3)CCl3 tetrahedra, and  an edgeedge with one Si(2)C2Cl2 tetrahedra. In the third Si site, Si(3) is bonded to one C(1), one Cl(3), one Cl(4), and one Cl(5) atom to form SiCCl3 tetrahedra that share  a cornercorner with one Si(1)CCl3 tetrahedra and corners with two equivalent Si(2)C2Cl2 tetrahedra. C(1) is bonded to one Si(1), one Si(3), and two equivalent Si(2) atoms to form edge-sharing CSi4 tetrahedra. There are eight inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Si(2) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Si(2) atom. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Si(3) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Si(3) atom. In the fifth Cl site, Cl(5) is bonded in a single-bond geometry to one Si(3) atom. In the sixth Cl site, Cl(6) is bonded in a single-bond geometry to one Si(1) atom. In the seventh Cl site, Cl(7) is bonded in a single-bond geometry to one Si(1) atom. In the eighth Cl site, Cl(8) is bonded in a single-bond geometry to one Si(1) atom.
