Introduction of ligands or spacers on phthalocyanine (Pc) structure was planned and confirmed by different physical techniques. Mononuclear structures, dimers & oligomers of 2,9,16,23-tetra(neopentoxy)phthalocyanine of cobalt (CoTnPc) (D4h) (high spin) and CoTnPc/L (C4v) (low spin) (L=axial ligand; i.e. cyanide, pyridine, 4-cyano-pyridine, pyrazine and 4,4'-bipyridyl) were preapred as solid compounds or as film structures and characterised by using elemental analysis, 1H NMR, IR and electronic spectra.
