Intramolecular Hydrogen

The stereochemistry of dl-glycerol 3-phosphate was studied by X-ray-crystallographic techniques. All the bond lengths and angles are within normally accepted limits except the ester bond, which is one of the largest yet noted, being 0.1637nm. The conformation of the molecule is such that an intramolecular hydrogen bond is formed between the hydroxyl group on the β-carbon atom and the phosphate group. The crystal, which was grown by alcohol diffusion into an aqueous solution, is held together by sodium co-ordination and a complex system of hydrogen bonds. A table of the observed and calculated structure factors, ǀFobs.ǀ and Fcalc., has been deposited as Supplementary Publication 50010 at the National Lending Library for Science and Technology, Boston Spa, Yorks.

Molecular Reactivity

Parameters of molecular reactivity (PRMs) it has been used by a group to foresee the reactivity of molecules that can be interesting in the formation of complex systems and introduce capacity potentially electron donors. It has also been used by a group, correlations of PRMs with other physical-chemistries properties as reaction enthalpy, energy-free from Gibbs, and of formation enthalpy. In this work, we made the study of the parameters of molecular reactivity (PRMs) for the molecules: Quinoline-N-Oxide (C9H7NO), Nicotinamide-NOxide (C6H6N2O2), and 2,2-Dithiobispiridine-N-Oxide (C10H8N2O2S2) and compared with measures of molar conductance. Our purpose was to observe in which greatness the conductance of a neutral ligand can influence the conductance of a complex system. Starting from the obtained data we observed that all the ligands studied in this work behave as nonelectrolyte in an aqueous solution, as expected, the second proposal based on the studies of ionic salts and pseudo-covalent, and, therefore we waited that should not influence significantly in the behavior electrolyte of complex systems formed with the same ones. Such expectations will be susceptible to practical confrontation through opportune experimental procedures.
