Sodium phthalocyanine (Na2Pc), potassium phthalocyanine (K2Pc) and hydrogen phthalocyanine (H2Pc) are synthesized in pure state. These complexes are characterized using physico-chemical methods like electronic, IR spectral, magnetic susceptibility measurements, thermogravimetric analysis and X-ray powder diffraction studies. Kinetic and thermodynamic parameters associated with the thermal decomposition were calculated using thermogravimetric analytical data. X-ray diffraction studies revealed that these complexes are having monoclinic crystal lattice structure. Electrical conductivity studies are carried out using two-probe technique in the temperature range 298–473 K for each complex. Sodium phthalocyanine showed semiconducting behavior, whereas potassium phthalocyanine showed first metallic behavior in the temperature range 300–378 K and then semiconducting property in the temperature range 383–473 K. But hydrogen phthalocyanine showed semiconducting behavior in the temperature range 300–390 K and metallic conduction behavior in the temperature range 395–473 K.
