Metallation of the low-symmetry 2-hydroxy-9(10),16(17),23(24)-tri-tert-butylphthalocyanine (ligand) with zinc and magnesium acetate salts in the medium of n-hexanol has resulted in obtaining the thermally stable dimeric J-type complexes constructed from identical macrocycles with a parallel orientation and geometrical rotation by an angle of 130–132 deg. Thermoanalytical study has demonstrated high stability (up to 450 ^оС) of dimeric complexes, and spectropotentiometry has identified significant differences in their nucleophilic properties as well.
