Synthesis, structural investigations and biological studies on symmetrically substituted 3,3,3",3"-tetra-methoxyphenylimino phthalocyanine complexes

The present paper describes the synthesis and characterization of novel metal (II) 3,3,3″,3-tetramethoxyphenylimino substituted phthalocyanines (M-MeOPhImPcs) of copper (II), cobalt (II), nickel (II) and zinc (II) by condensing the 3,3,3,3″-tetra amino phthalocyanines with anisaldehyde. The dark bluish green colored tetraimino substituted phthalocyanine derivatives were characterized by various physico-chemical techniques like elemental analysis, magnetic susceptibility, electronic, IR, powder X-ray diffraction and thermo gravimetric analysis (TGA) to check the structural integrity and purity. The variations of magnetic moment as a function of field strength indicated the presence of inter molecular co-operative interactions. The complexes were also evaluated for their antifungal and antibacterial activities.
