Abstract

Metallophthalocyanine (M = Cu, Co, Ni and Zn) carrying eight (3-bromophenyl) methanimine groups at peripheral positions were synthesized by an efficient, simple and novel method. The precursor octaamino metal(II) phthalocyanines were synthesized by the reduction of the corresponding nitro metal phthalocyanines. The dark green octa-1-(3- bromophenyl)methanimine phthalocyanine derivatives were characterized by elemental analysis, magnetic susceptibility, electronic, IR and powder x-ray diffraction studies to check the purity, structural integrity and crystalline properties of the complexes. Magnetic susceptibility studies on Co(II) and Cu(II) octa-1-(3-bromophenyl) methanimine phthalocyanine complexes exhibit a variation of the magnetic moments as a function of field strength indicating the presence of inter molecular co-operative effect.
