Structures citing

Finally, a new class of antispermatogenic agents containing the same fundamental structure cited above has been described (76JMC778). 1-Halobenzyl-l J/-indazole-3-carboxylic acids are potentially useful for birth control, and because they act after a single administration they are of interest for the physiological study of the male reproductive system. 

In the structures cited in Table 12.3, except for pure silicon dioxide, metal ions are required for overall electrical neutrality. These metal ions are positioned in tetrahedral, octahedral, etc. positions in the silicate-like lattice. Sometimes they replace the silicon atom. Kaolinite asbestos has aluminum substituted for silicon in the Gibbosite sheet. Further, sites for additional anions, such as the hydroxyl anion, are available. In ring, chain, and sheet structures neighboring rings.

In the Pauling theory of its structure, guanidine is a resonance compound of the molecular structure cited (NH,) C=NH] and two ionic structures in which the nitrogen of the imino group gains an electron lost by one of ihe amino groups. 

In summary, all the available chemical, biochemical, and physicochemical evidence is in harmony with the structure cited above for raffinose. 

The cocrystal structures cited above provided no evidence of G-quartets or G4 DNA formed within the G-rich telomeric DNA complexed to the protein. While a higher resolution structure (1.86 A) of the Oxytricha telomere endbinding complex identified G-quartets stabilizing antiparallel interactions... 

The diversity of the structures cited suggest that the subject of supramolecular association in organotin carboxylato derivatives is far from being exhausted, and novel interesting structures can be expected from the use of new carboxylic acids. 

The regularities in the pair structure cited above follow immediately by substituting the appropriate J, values in the last formula.
