Abstract
Mass spectra of various phthalocyanines (metal free, iron, cobalt, nickel, copper, zinc, platinum, di-chloro germanium and di-hydride geranium) were measured by electron impact ionization mass spectrometry (EI-MS). When the mass spectra of the mixture of the phthalocyanines and K2PtCl6 were measured, the hydrogen atoms of the phthalocyanine ring were substituted by chlorines and one or two chlorines were added to the metal. The number of chlorine atoms reacted with the phthalocyanines are shown in the parenthesis below and their order is:
H2(3) < Ni(9) < Pt(11) < Co(16), Cu(16) < Fe(17), Zn(17) < Ge(18).
In the case of Ge(pc)H2, the ion (Ge(pc)H2 + H)+ was observed both by EI and FD techniques.
