Abstract. Quantum chemical calculation of the molecules of 3,5-di(cyclo-trialumoxandiol)tetraalumoxantetraol-1,1,7,7and 1,7-di(cyclotrialumoxandiol)tetraalumoxantetraol-1,3,5,7 is executed for the first time by method MNDO with optimization of geometry on all parameters by standardgradient method. The optimized geometrical and electronic structure of these compounds is received. Acid force of 3,5-di(cyclo-trialumoxandiol) tetraalumoxantetraol-1,1,7,7and 1, 7-di(cyclotrialumoxandiol)tetraalumoxantetraol-1,3,5,7 is theoretically appreciated. It is established, that it to relate to a class of very weak H-acids (pKa=14) where pKa-universal index of acidity).
Key words: quantum chemical calculation, method MNDO,3,5-di(cyclo-trialumoxandiol)tetraalumoxantetraol-1,1,7,7, 1,7-di(cyclotrialumoxandiol)tetraalumoxantetraol-1,3,5,7, acid force.
The Aim of this work is a quantum chemical calculation and theoretically determination of acid force of derivativesdioles3,5-di(cyclotrialumoxandiol) tetraalumoxantetra-ol -1,1,7,7 and 1,7-di(cyclo trialumoxan-diol)tetraalumoxantetraol-1,3,5,7 by method MNDO with optimization of geometry on all parameters by standard gradient methodbuilt-in in PC GAMESS [10]. The calculation was executed in approach the insulated molecule in gas phase. Program MacMolPlt was used for visual presentation of models of molecules [9].These compounds can be fragments of polymermodels of optical glasses, such as «low-crownglass» and «heavyflint glass».
Results of the calculation
Optimized geometric and electronic structures, general and electronic energies of molecules3,5-di(cyclotrialumoxandiol)tetra-alumoxantetraol-1,1,7,7and 1,7-di(cyclo-trialumoxandiol)tetraalumoxantetraol-1,3,5,7 were received by method MNDO and are shown on fig. 1,2 and in tabl. 1-3. The universal factor of acidity was calculated for method MNDO by formula: pKa=42.11-147.18qmaxH+[1-8; 11] (where, qmaxH+ " a maximum positive charge on atom of the hydrogenqmaxH+= 0.19pKa- pKa-universal index of acidity (tabl.1).pKa = 14.
