    Description / Table of Contents: Synthesis und Properties of Bis(tetra-n-butylammonium)-fluoro-phthalocyaninato-hydrogenate-pentahydrateDarkgreen cubic crystals (a = 21.446(10) Å) of bis(tetra-n-butylammonium)-fluoro-phthalocyaninatohydrogenate-pentahydrate, (Bu4N)2[HFPc(2-)] · 5H2O, are prepared by the reaction of H2Pc(2-) with excess (Bu4N)F · 3H2O preferably in dichloromethane or pyridine. The thermal analysis shows two endothermic losses in weight corresponding to the evaporation of crystal water at T 〉 125°C and the decomposition of the complex salt giving H2Pc(2-) at T 〉 180°C, respectively. The electrochemical (cv) and spectroscopical properties (uv-vis, i.r., resonance Raman, 1H, 13C, and 19F nmr spectra) are investigated and the characteristic differences with those of H2Pc(2-) are discussed.
    Notes: Dunkelgrüne, kubische Kristalle (a = 21,446(10) Å) von Bis(tetra-n-butyl-ammonium)-fluoro-phthalocyaninatohydrogenat-pentahydrat, (Bu4N)2[HFPc(2-)] · 5H2O, werden durch die Umsetzung von H2Pc(2-) mit überschüssigem (Bu4N)F · 3H2O bevorzugt in Dichlormethan oder Pyridin dargestellt. Die thermische Analyse zeigt zwei endotherme Gewichtsverluste, die bei T 〉 125°C der Abgabe des Kristallwassers und bei T 〉 180°C der Zersetzung des Komplexsalzes unter Bildung von H2Pc(2-) entsprechen. Die elektrochemischen (CV) und spektroskopischen Eigenschaften (UV-VIS-, IR-, Resonanz-Raman-, 1H-, 13C- und 19F-NMR-Spektren) werden beschrieben und mit denen von H2Pc(2-) verglichen.
