Paper Abstract

The results of systematic theoretical studies of molecular structure, charge distribution and bond characteristics (bond lengths and bond orders) of potassium - magnesium aspartates ((Asp¯)3 K+ Mg2+) in aqueous solution obtained by ab initio quantum-chemical method are presented. The supermolecules including (Asp¯)3 K+ Mg2+ + nH2O + (n = 20, 40, 60, 100;) were considered. In all the cases supermolecule structure were optimized by using the total energy minimization of the system. The features of a structure of associates formed as a result of interaction of potassium and magnesium aspartates with molecules of water are studied. Is was shown, that in the aqueous solution K and Mg aspartates form stable complexes, the structural elements in which are joined by electrostatic interaction.
