Abstract. Quantum chemical calculation of the molecules of 3,5-di(cyclotrialumoxandiol) 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(cyclotrialumoxandiol) tetraalumoxantetraol-1,1,7,7, 1,7-di(cyclotrialumoxandiol)tetraalumoxantetraol-1,3,5,7, acid force.
