Synthesis and structural studies of metal(II) 4,9,16,23-phthalocyanine tetraamines
1987
Preparation of pure metal(II) 4,9,16,23-phthalocyanine tetraamine 2-hydrates of copper, cobalt, nickel and zinc are reported. Elemental analysis, electronic spectra, FT-IR spectra, powder X-ray diffraction, magnetic-susceptibility measurements, dynamic thermogravimetric MS and GC-MS spectral studies are carried out to check the purity, structural integrity, thermal stability and mode of fragmentation of these complexes. Magnetic-susceptibility measurements showed a variation in the magnetic moments of these complexes with magnetic field strength, indicating the presence of a co-operative intermolecular effect.
