 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-).

Linear-bis(triphenylphos-phine)iminium frans-bisnitro-phthalocyaninatoiridate(III) (l(PNPy™,,v[Ir(/V02)2pc2"]) is pre­ pared by air-oxidation of [(Irpc2')2] in dichloromethane in the presence of (P N P)N 0 2. It crystallizes in the triclinic space group P I (no. 2) with the following cell parameters: a -10.649(1) Ä, b = 12.357(1) A, c = 12.841(1) A, a = 75.47(1)°, ß = 67.88(1)°, y = 65.31(1)°, Z = 1. Ir111 is in the centre of a slightly waving pc2~ ligand coordinating two nitro ligands in an eclipsed fram-arrangement. The average Ir-Niso distance is 1.993(2) A (N iso: isoindole N atom), the Ir-N distance is 2.189(3) A (N: nitrite N atom), respectively. The structural data of the nitrite ion are: d(ZV-O) = 1.194(4) and 1.042(5) A, Z(O -N -O) = 131.7(4)°). Spectral properties with diagnostic IR absorption bands at 820, 1331 and 1398 cm -1 confirm the nitro coordination.

 Abstract    und Eigenschaften von Tetra(w-butyl)ammonium-c/s-diacidooxophthalocyaninato(2-)niobaten(V) und -tantalaten(V); Kristallstruktur von (wBu4N)CIS[Nb(F)20pc2'] Preparation and Properties of Tetra(«-butyl)ammonium c/'s-Diacidooxophthalocyanina-to(2-)niobates(V) and -tantalates(V); Crystal Structure of ("Bu4N)m [Nb(F)2Opc2~j Tetra(n-butyl)ammonium ds-diacidooxophthalocyaninato(2-)niobates(V) and -tantalates(V), (''Bu4N)m [M(X)2Opc2~] (M = Nb, Ta; X = F, Cl, NCS, N3), are obtained by the reaction of m [M(Cl)3pc2~] or m [M(Cl}Opc2~] (M = Nb, Ta) with the respective tetra(n-butyl)ammonium salt. ('!Bu4N)c'v[Nb(F)oOpc'_ ] crystallizes in the monoclinic space group P2\tn with cell pa­ rameters a = 13.460(5'), b = 13.820(5), c = 23.360(5) Ä, ß = 92.640(5)°, Z = 4. The hepta-coordinated Nb(V) atom is surrounded by four isoindole nitrogen atoms (Niso) of the pc2~ ligand, two fluorine atoms and one oxygen atom in a distorted square-base-trigonal-cap poly­ hedron. Nb(V) is displaced out o fothe centre of the (N,.s")4 plane (Ct(N,.so)) towards the acido ligands (d(Nb-Ct(Niso)) = 1.241 A). The average (Nb-NIJO), (Nb-F), and (Nb-O) distances are 2.300, 1.957, and 1.720(5) A, the (F-Nb-F) and the average (O-Nb-F) angles are 79.8(2) and 91.8°, respectively. The pc2_ ligand is concavely distorted. Typical 7r-7r*-transitions of the pc2~ligand are observed in the UV/Vis spectra at ca. 14500 and 29300 cm-1 . Vibration frequencies t/asiS(M-X), ^(M-O) and (5(X-M-0) have been assigned.
