 Abstract    -und dreikemige Organometallkomplexe (ReS4)[MCl(C5Me5)], M = Rh, Ir, und (/x-WS4)[IrCl(C5Me5)]2 Dinuclear and Trinuclear Organometallic Complexes (ReS4)[MCl(C5Me5)], M = Rh, Ir, and (Ai-WS4)[IrCl(C5Me5)]2 The reactions of tetrathiorhenate(VII) or tetrathiotungstate(VI) with [MCl2 (C5 Me5)]2, M = Rh or Ir, yield the neutral title compounds of which (ReS4)[RhCl(C5 Me5)] and (/a-WS4)[IrCl(C5 Me5) ] 2 could be crystallographically characterized. The molecules contain nearly tetrahedral M'S4 units and rhodium(III) or iridium(III) centers with piano stool geometry. Weak intermolecular (M)C1--H(Me) interactions are observed in the crystals. Vibrational and elec­ tronic spectra are in agreement with the structures, illustrating p—d charge transfer interactions between the sulfide or chloride donors and the d° or d6 metal acceptor centers, respectively. Oxidation and reduction of the compounds occur completely irreversibly.

 Title    Synthese von Bis[pyridin-phthalocyaninato(l,5-)iridium(II)]iodid und Pyridin-iodo-phthalocyaninato(2-)iridium(III)-Pyridin durch schrittweise Oxydation von Bis[pyridin-phthalocyaninato(2-)iridium(II)]  
 Abstract    Synthesis of Bis[pyridine-phthalocyaninato(l,5-)iridium(II)] Iodide and Pyridine-iodo-phthalocyaninato(2-)iridium(III)-Pyridine by Successive Oxidation of Bis[pyridine-phthalocyaninato(2-)iridium(II)] Successive oxidation of bis[pyridine-phthalocyaninato(2-)iridium(II)] with iodine first yields mixed-valent bis[pyridine-phthalocyaninato(l,5-)iridium(II)] iodide ([(Ir(py)pc1 5'}2]I) and then pyridine-iodo-phthalocyaninato(2-)iridium(III)-pyridine ([Ir(py)(I)pc2_]-py). The latter crystallizes monoclinically with the following cell parameters: a = 10.258(1) A. b = 17.589(3) Ä, c = 19.723(2) Ä, ß = 92.95(1)°, space group P2j/n, Z = 4. Irm is in the centre of a slightly distorted pc2 ligand and coordinates pyridine and iodide in a fra/zs-arrangement. The average Ir-Niso distance is 1.995(5) A (Niso: isoindole N atom), the Ir-Npy and Ir-I distan­ ces are 2.102(5) and 2.657(1) A, respectively. By a similar oxidation of [{Rh(py)pc2 }2] only [Rh(py)(I)pc2~ ] py is obtained. Solid state spectral properties with diagnostic absorption bands at 1360. 1456, 5620 and 19800 cm-1 confirm the mixed-valent diphthalocyaninate(1.5-).
