Symmetrically octasubstituted metal(II) [M = Cu, Ni, Co, and Zn] 1,3,8,10,15,17,22,24-aminophthalocyanines have been synthesized by an efficient, simple and novel method. The aminophthalocyanines were synthesized by the reduction of the corresponding nitrophthalocyanines. The dark blue-green octaaminosubstituted phthalocyanine derivatives were characterized by elemental analyses, magnetic susceptibility, electronic, IR, thermal, and powder X-ray diffraction studies to check the purity, structural integrity, thermal stability and crystallinality of the complexes. Magnetic susceptibility studies on the above octaaminophthalocyanine complexes show a variation of the magnetic moments as a function of field strength indicating the presence of intermolecular cooperative effects. Thermal studies revealed that the complexes are stable up to 400 degreesC in air, and powder X-ray diffraction studies have shown that they are crystalline in nature.
