摘要：
The quantum chemical (U)B3LYP/6-31G(d5,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 (D4h) structure with a rectangular AlOAl group and a retarded low-symmetry (Cs) 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.
