| Phthalocyanines on Mineral Carriers, 2* Synthesis of Cobalt(II) and Copper(II)-phthalocyanines on y-Al20 3 and S i0 2  | | | | Abstract
| The reaction o f metal loaded y -A l20 3 and S i 0 2 with benzene-1,2-dicarbonitrile (2) resp. 1H-isoind ole-l,3(H)diim ine (3) results in the /^-modification o f m etallized phthalocyanines (1; metals: C u(II), C o(II)). 1 is form ed with an average yield o f 4 8 —64% in uniform distribution on the carriers from the reaction with 2. The sizes o f the surface areas of the supports are not changed significantly by loading with 1. Non-uniform distribution or even unsupported crystals o f 1 are found if the synthesis is carried out with 3. | | | |

| Darstellung, Eigenschaften und elektronische Raman-Spektren von Di(bromo)phthalocyaninatometallaten(III) der Eisengruppe | | | | Abstract
| Synthesis, P ro p erties an d E lectronic R am an Spectra of D i(b ro m o)p h th alo cy an in ato m etalates(III) of the Iron G roup E lem ents Svend Sievertsen, H en d rik Schlehahn, H ein er H om borg Low spin di(bromo)phthalocyaninatometalates of tervalent iron, ruthenium and osmium ([MBr2Pc2-]') are formed by the reaction of [FeBrPc2~] or H[MBr2Pc2 ] (M = Ru, Os) with ex cess bromide in DMF or THF and isolated as ("Bu4N)+ salts. The electronic spectra show the typical J i-jr*-transitions (B, Q, N region) of the Pc2~ ligand together with a number of extra bands due to trip-multiplett and (Pc, Br — » M)CT transitions. vs(MBr) is observed in the resonance Raman (RR) spectrum (RR enhanced for M = Fe, Ru) at 161 cm-1 (Fe), 183 cm4 (Ru) and 192 cm-1 (Os), vas(MBr) at 251 cm4 (Fe), 234 cm-1 (Ru) and 218 cm-1 (Os) in the FIR spectra. The RR spectra obtained by excitation at low absorbance between the B and Q region are dominated by the intraconfigurational 'T 7 — > r 8" transition due to spin orbit split ting of the 2T2g ground state for Fe at 583 cm-1, Ru at 1026/1050 cm-1 and Os at 3131 cm4 . In the MIR resp. NIR spectra vibronically induced transitions are observed for the Ru or Os complex. | | | |

| Darstellung von Phthalocyaninen von Ib-Elementen in aprotischen Lösungsmitteln Preparation of Phthalocyanines of lb-Elements in Aprotic Solvents | | | | Abstract
| The double decomposition of (TDBA)LiPc(2-) with halocomplexes of the lb-elements is investigated in nonpolar aprotic solvents. Phthalocyanines of the formula MLiPc(2-) are isolated only for the univalent cations Cu(I) and Ag(I), but not for Au(I). The impure AgLiPc(2-) is light sensitive. In contrast to earlier observations only oxidation products of the phthalocyanine anion are obtained in the presence of Cu(II) and Au(III). The preparation of Ag(II) and Au(II) phthalocyanines failed.
