Dimeric silicon dioxide, (SiO 2) 2 has been prepared by reacting O 2 with matrix isolated dimeric silicon monoxide, (Si 2 O 2). In dimeric silicon dioxide there are two oxygen atoms bridging between the silicon atoms with an SiOSi angle of 94° and bond length of pm and the terminal SiO bond length is pm.
