Abstract

Symmetrically substituted metal(II) (M ¼ Cu, Co, Ni, Zn)-1,3,8,10,15,17,22,24-octaiminophthalocyanines (M-ImPcO) were synthesized using an efficient, simple and novel method via the reduction of the corresponding nitro phthalocyanines. The dark green octaiminophthalocyanine derivatives were characterized by elemental analysis, magnetic susceptibility, electronic, IR and powder X-ray diffraction studies to check the purity, structural integrity and crystallinity of the complexes. Magnetic susceptibility studies of the Co(II) and Cu(II) octaiminophthalocyanine complexes revealed a variation in magnetic moments as a function of field strength indicating the presence of intermolecular co-operative effect. The complexes were screened for antifungal activity.
