The above trends persist when the more spacious C60H24 (T) cage is used, but the shifts of the guest frequencies v and constants a are noticeably smaller than forMH4 C6oH36-... [Pg.85]

Now we discuss results of our DFT study of another series of model end-ofullerenes containing tetrahedral anions MOnA (M = Si, P, S, Cl, Ar and N) with 32 valence electrons inserted into the C60H36 (T) cage [58], where... [Pg.86]

However, MALDI-TOF MS gave the considerably lower ion mass peak at 6867 m/z ([M+Na]+) than expected (7658 m/z as [M]+). It is not clear whether such inconsistency was caused by the incomplete structure of the compound, or by the decomposition of the compound in MS analysis. Because quantitative analysis of the ratio of A and T cages was not possible due to the absence of proton signal of the Q cage, and inconsistent values in MS analysis were obtained, we admit that there is still doubt about the accurate structure of the product. Nevertheless, we can conclude that a higher order POSS structure was constructed from T4 and Q cores. [Pg.224]

Starting from any of those low-Iying isomers of the T-cage the three-dimensional periodic lattice of the (si) hydrate can now be constructed. In the 46-moIecuIe unit ceU of the (si) lattice... [Pg.785]

Schematic approach for building the (si) hydrate lattice from the low-lying networks of the T-cage. The connectivity of the O atoms between the two cages (without hydrogen atoms) is highlighted in gray. The blue box indicates the (si) cubic unit cell (46 water molecules).
