Abstract

Si6O7Cl10 crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two decachlorobicyclo[5.5.1]tridecanehexasiloxane molecules. there are four inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to three O2- and one Cl1- atom to form corner-sharing SiClO3 tetrahedra. All Si–O bond lengths are 1.63 Å. The Si–Cl bond length is 2.02 Å. In the second Si4+ site, Si4+ is bonded to two O2- and two Cl1- atoms to form corner-sharing SiCl2O2 tetrahedra. Both Si–O bond lengths are 1.62 Å. Both Si–Cl bond lengths are 2.03 Å. In the third Si4+ site, Si4+ is bonded to two O2- and two Cl1- atoms to form corner-sharing SiCl2O2 tetrahedra. There is one shorter (1.62 Å) and one longer (1.63 Å) Si–O bond length. Both Si–Cl bond lengths are 2.03 Å. In the fourth Si4+ site, Si4+ is bonded to three O2- and one Cl1- atom to form corner-sharing SiClO3 tetrahedra. There is one shorter (1.62 Å) and two longer (1.63 Å) Si–O bond length. The Si–Cl bond length is 2.03 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the third O2- site, O2- is bonded in a linear geometry to two Si4+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Si4+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Si4+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Si4+ atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Si4+ atom. In the fifth Cl1- site, Cl1- is bonded in a single-bond geometry to one Si4+ atom. In the sixth Cl1- site, Cl1- is bonded in a single-bond geometry to one Si4+ atom.
