Abstract
Two novel tungsten phthalocyanine compouds have been synthesized. Chlo ro(phthalocyaninato)tungsten(II), (ClPc)W, was prepared by deoxygenati on of chloro(phthalocyaninato)(oxo)(hydroxo) tungsten(V), (ClPc)W(O)(O H). Magnetic susceptibility studies indicate that (ClPc)W is diamagnet ic and (ClPc)W(O)(OH) paramagnetic. EPR data suggests that chlorine is attached to the isoindole unit of the phthalocyaninato ligand, and no t to tungsten. These data, together with the chemical analysis, infrar ed spectra, and visible absorption spectra clearly define the chemical composition and tungsten oxidation states in these new metallophthalo cyanines.
