    Notes: The SO2 coordination mode at the rhodium complex [ClRh(P∼O)()] (1) [ = η2(O,P)-chelated Cy2PCH2CH2OCH3 ligand; P∼O = =1(P)-coordinated] is controlled by the hemilabile ligand Cy2PCH2CH2OCH3 and shows a dependence on the polarity of the solvent. In polar organic solvents (e.g. acetone) the addition of sulfur dioxide results in the formation of a trigonal-pyramidal oriented SO2 group in [ClRh(η1-SO2)(P∼O)()] (2a). However, in nonpolar media (e.g. n-hexane) a trigonal-coplanar geometry of the SO2 unit in [ClRh(η1-SO2)(P∼O)2] (2b) is favored.

    Description / Table of Contents: (Phthalocyaninato)iron(II)- and -ruthenium(II) Compounds with Isocyanides as Axial Ligands(Phthalocyaninato)iron(II) and -ruthenium(II) (PcM, M = Fe, Ru) react with aliphatic and aromatic monodentate isocyanides RNC (R = t-Bu, c-Hx, Bzl, Ph, Me2ph) with formation of the corresponding bisaxial substituted (phthalocyaninato)metal(II) compounds PcM(RNC)2 (M = Fe, Ru) 1 - 5. The structures of these soluble compounds were determined by 1H and 13C NMR spectroscopy. The influence of the central metal atom M and of the organic group on the σ-donor-π-acceptor properties of the metal-ligand bond is investigated by IR spectroscopy. UV/VIS spectroscopy, TG/DTG/DTA measurements and FD mass spectroscopy additionally demonstrate the large differences when changing iron against ruthenium in 1 - 5. The thermal and mass spectroscopic differences point to the existence of pentacoordinated PcRu(II) compounds.
    Notes: (Phthalocyaninato)eisen(II) und -ruthenium(II) (PcM, M = Fe, Ru) reagieren mit aliphatischen und aromatischen einzähnigen Isocyaniden RNC (R = t-Bu, c-Hx, Bzl, Ph, Me2ph) zu den entsprechenden bisaxial substituierten (Phthalocyaninato)metall(II)-Verbindungen PcM(RNC)2 (M = Fe, Ru) 1 - 5. Die Strukturen dieser löslichen Verbindungen werden durch 1H- und 13C-NMR-Spektroskopie bestimmt. Der Einfluß des Zentralmetalls M sowie des organischen Restes R auf die σ-Donor- bzw. π-Akzeptor-Eigenschaft der Metall-Ligand-Bindung wird IR-spektroskopisch untersucht. UV/VIS-Spektroskopie, TG/DTG/DTA-Untersuchungen und FD-Massenspektroskopie verdeutlichen zusätzlich die starken Unterschiede beim Austausch von Eisen durch Ruthenium in 1 - 5. Die thermischen und massenspektroskopischen Untersuchungen ergeben konkrete Hinweise auf die Existenz pentakoordinierter PcRu(II)-Verbindungen.

    Description / Table of Contents: Monomeric and Bridged (Phthalocyaninato)iron(II) and -ruthenium(II) Compounds with 2,3,5,6-Tetramethyl-1,4-diisocyanobenzene (Me4dib) and 2,3,5,6-Tetrachloro-1,4-diisocyanobenzene (Cl4dib) as Axial LigandsThe reaction of the bidentate ligand 2,3,5,6-tetramethyl-1,4-diisocyanobenzene (Me4dib) with (phthalocyaninato)iron(II) and -ruthenium(II) (PcM, M=Fe, Ru) yields, depending on the reaction conditions, bisaxially coordinated monomeric derivatives of the stoichiometry PcM(Me4dib)2; 1, M=Fe; 2, M=Ru, or one-dimensional bridged polymeric chain structures of the formula [PcM(Me4dib)]n; 3, M=Fe; 4, M=Ru. 2,3,5,6-Tetrachloro-1,4-diisocyanobenzene can also be used as coordinative ligand to form the polymers 5-7. Synthesis of 3 and 4 is also possible starting with 1 and 2 in solution or in solid state. The polymerization in solution can be followed by 1H NMR spectroscopy. The intermediates formed are structurally characterized. The structures 1-7 are in agreement with additional TG/DTG/DTA-, 57Fe-Mößbauer, and IR measurements. Despite large differences in dc conductivity of the parent compounds PcFe and PcRu, the ligand-bridged compounds [PcML]n (L = bidentate ligand) exhibit almost similar conductivities.
    Notes: Die Umsetzung des zweizähnigen Liganden 2,3,5,6-Tetramethyl-1,4-diisocyanbenzol (Me4dib) mit (Phthalocyaninato)eisen(II) und (Phthalocyaninato)ruthenium(II) (PcM, M=Fe, Ru) führt je nach Reaktionsbedingung zu bisaxial koordinierten monomeren Derivaten PcM(Me4dib)2; 1, M=Fe; 2, M=Ru, oder zu den überbrückten Komplexen [PcM-(Me4dib)]n; 3, M=Fe; 4, M=Ru, mit eindimensionaler Kettenstruktur. Mit 2,3,5,6-Tetrachlor-1,4-diisocyanbenzol (Cl4dib) als Liganden werden die Polymeren 5-7 erhalten. Die Darstellung von 3 und 4 ist auch ausgehend von 1 und 2 durch Reaktion in einem Lösungsmittel oder thermisch als Festkörperreaktion möglich. Der Verlauf der Polymerisation in Lösung kann 1H-NMR-spektroskopisch verfolgt, und die gebildeten Zwischenprodukte können charakterisiert werden. Die Strukturen 1-7 stehen in Einklang mit den zusätzlichen TG/DTG/DTA-, 57Fe-Mößbauer- und IR-Untersuchungen. Trotz stark unterschiedlicher Leitfähigkeit der unkoordinierten Metallmakrocyclen PcM führt deren Umsetzung zu [PcML]n (L = zweizähniger Ligand) zu einer Angleichung ihrer Leitfähigkeiten.
