Abstract
Using 1-aminoadamantane a new type of silica host framework has been stabilized. The clathrasil is rhombohedral with a = 13.887Å and c = 40.989Å for the hexagonal unit cell. Heating the compound on a thermal analyser shows that from 500°C on the guest molecule evaporates. The silica framework only very slowly breaks down when heated at 1100°C for several hours yielding cristobalite. Since 1-aminoadamantane stabilizes,at higher temperatures of synthesis,dodecasil 1H the new clathrasil is regarded as low temperature form for this particular guest molecule.
