Massenspektrometrische Untersuchungen von PhthalocyaninenPc—MeX n

PhthalocyaninesPc?Me(III)X andPc?Me(V)X ₃ were obtained by reacting anhydrous metal halides with phthalodinitrile and di-lithium-phthalocyanine, resp. A phthalocyanine containing niobium(V) was prepared for the first time. Mass spectrometric investigation of the products formed show the molecular ion in the case of chloro-aluminum-, chloro-indium- and tribromo-niobium-phthalocyanine. The mass spectra of chloro-scandium-, chloro-yttrium- and tribromo-tantalum-phthalocyanine showed neither peaks of the molecular mass nor metal containing fragments of the phthalocyanine structure. Mass spectrometric results seem to depend critically on the purity of the compounds employed.
