Three new substituted manganese phthalocyanines (PcMns), wich are water-soluble, have been synthesized with good yields (70–80%) and high purity. Pyridiniummethyl- and cholinylsubstituted phthalocyanines have been obtained from the chloromethylsubstituted PcMns, while octacarboxysubstituted complex has been synthesized from metal-free octacarboxyphthalocyanine tetraanhydride. Compounds were characterized by elemental analysis and mass, IR and UV-vis spectroscopy. In general, coordination chemistry of the compounds studied is similar to this one of liposoluble PcMns but some new findings have been obtained. Three coordination forms — PcMn(II), PcMn(III)X(X = Cl^-, OAc^-, …) and [LPcMn(III)]₂O(L = Py, Et₃N, …) have been obtained for all the new compounds. The equilibrium between three electronic isomers — Pc^+•Mn(I) × L, PcMn(II) × nL, (n = 1, 2) and Pc^-•Mn(III) × 2L has been observed in PcMn aqueous solutions upon the addition of organic bases L (Py, Et₃N, …).
