Vibrational Spectra and X-Ray Structure Analysis o f (Cl2SiO) 3 and (Cl2SiO) 4  | | | Abstract
| Hexachlorocyclotrisiloxane (2) and octachlorocyclotetrasiloxane (4) were prepared by reac tion o f SiCl4 with 0 2 at 955 C. Their mass spectra are compared with those o f the isoelectronic cyclophosphazenes. The vibrational spectra o f 2 and 4 are very similar and closely related to that o f (PNC12)3, but clearly different from that o f the puckered (PNCU) 4 molecule. The X-ray examination o f 2 and 4 reveals planarity o f the (SiO)", n = 3 and 4 ring systems, with d (S i-O) on average 1.619(4) and 1.584(3) Ä, respectively. | | |
