SILICA POLYMORPHS & ZEOLITES

Each of the silica polymorphs could be turned in to their corresponding 2-,4-connected C allotropes by replacing the Si atoms with tetrahedral 4-connected C atoms and replacing the 2-connected O atoms with 2-connected acetylenic spacer groups thus. Also the zeolites could be dealt with in the same manner as the silica polymorphs, and the silica polymorphs and the numerous zeolites could have all 2-connected O linkages excised from the corresponding networks, and then one joins all corresponding 4-connected tetrahedral Si atoms etc. and one thus turns them in to tetrahedral C atoms...MJB
