Octachloro- and hexadecafluoro-substituted lanthanide(III) monophthalocyaninates, which have not been described earlier, were obtained based on the corresponding nitriles using the template method. The possibility of both thermal and microwave activation of cyclization process was demonstrated. All target compounds were identified by MALDI TOF mass spectrometry, FTIR and 1H NMR spectroscopy. Strong downfield lanthanide-induced shifts of signals of aromatic protons were observed in the nuclear magnetic resonance spectra of europium and erbium complexes comparing with diamagnetic lutetium one. Bathochromic shift of the Q band (about 20 nm) was observed for hexadecachloro-substituted compounds comparing to octachloro-substituted analogs.
