Abstract: | Preparation and Properties of Phthalocyaninato(2–)indates(III) with Monodentate Acido Ligands; Crystal Structure of Tetra(n-butyl)ammonium cis -Difluorophthalocyaninato(2–)indate(III) Hydrate Tetra(n-butyl)ammonium cis-diacidophthalocyaninato(2–)indates(III) with the monodentate acido ligands fluoride, chloride, cyanide and formiate are synthezised by the reaction of chlorophthalocyaninatoindium(III) or cis-dihydroxophthalocyaninatoindate(III) with the respective tetra(n-butyl)ammonium salt or ammonium formiate and are characterized by their UV/VIS spectra and their vibrational spectra. The difluoro-complex salt crystallizes as a hydrate ((nBu4N)cisIn(F)2pc2–] · H2O) in the monoclinic space group P21/n (no. 14) with cell parameters: a = 13.081(3) Å, b = 13.936(2) Å, c = 23.972(2) Å; β = 97.79(1)°, Z = 4. Hexa-coordinated indium is surrounded by four isoindole nitrogen atoms (Niso) and two cis-positioned fluorine atoms. The average In–F and In–Niso distance are 2.0685(4) and 2.2033(5) Å, respectively, and the F–In–F angle is 81.5(1)°. The In atom is displaced outside the centre (Ct) of the Niso plane towards the fluoride ligands: d(In–Ct) = 0.953(1) Å. The phthalocyaninato(2–) core is nonplanar (unsymmetrical concave distortion). |
