The complexes of peripherally tetra-substituted metal-free (8), lead(II) 9), and zinc(II) (10) phthalocyanine derivatives were synthesized for the first time in this work. The structures of these new complex compounds have been elucidated using many spectral methods such as electronic absorption, FT-IR, $^{1}$H NMR, $^{13}$C NMR, elemental analysis, and mass spectra. The thermogravimetric behavior of compounds 8-10 was determined by thermogravimetric analysis method in addition to these spectral methods.
