The stability of a metal phthalocyanine coordination compound depends on the size of the intercalated metal cation. When a copper, nickel, zinc, cobalt, aluminum, platinum, or iron anion is inserted in the phthalocyanine ring, the resulting complex is quite stable. For example, unsubstituted copper-phthalocyanine is mainly used as blue pigment while substituted phthalocyanines are used as dye. However, the out of plane intercalation of sodium, potassium, calcium, barium, or mercury cations which are to big to fit into the cavity of the phthalocyanine macrocycle is possible but the resulting coordination compounds are quite unstable and such metal phthalocyanines can be easily converted into metal-free phthalocyanine (H2Pc) which is also a valuable pigment whose color is a little bit more greenish than the copper phthalocyanine. Halogenated phthalocyanines are bright green pigments.

The ring of phthalocyanine has π-electrons that can move via π-electron cloud overlaps; therefore high conductivity can occur. In fact, metal phthalocyanines are known to form conducting solids when the π-ligand is oxidized. Partially oxidized complex salts of [MPc]X (M = H2, Ni, Cu, etc.; Pc = phthalocyanine; X = I, (BF4)0.33, (SbF6)0.5,etc) are known to be metallic one-dimensional conductors. The crystals consist of one-dimensional face-to-face stacked phthalocyanine columns and one-dimensional anion chains.
