The quantum chemical (U)B3LYP/6-31G(d ₅,p) method is used to determine the structural parameters and ionization potentials of aluminum(III) (μ-oxo)bis[phthalocyaninate] and monophthalocyaninate PcAlCl. Two (PcAl) ₂O structures with similar energies are obtained: an eclipsed high-symmetry (D _4h) structure with a rectangular AlOAl group and a retarded low-symmetry (C _s) structure with the AlOAl bond angle of 167.5°. The AlO bonds include a substantial π component. The energy needed for the detachment of two electrons from a free (PcAl) ₂O molecule is 13.46 eV. Original Russian Text
