 Title    X-Ray Structure of a Nickel(II) Complex of the Tetra-N-methylated Macrocycle Dibenzocyclam with a Folded Ligand Configuration  
 Abstract    X -R ay, N ickel(II) C om plex, N 4 M acrocycle Tetra-N-M ethyl Dibenzocyclam , Folded Configuration o f N 4 M acrocycle U nder mild conditions nickel(II) nitrate reacts with the macrocyclic N 4 ligand TM BC (= l,4 ,8 ,ll-tetra m eth y l-l,4 ,8 ,ll-tetra a za d ib en zo [b ,i]cy clo tetra d eca n e) to form the light blue-green com plex Ni (TM BC) (N 0 3) 2. A three-dim ensional X-ray diffraction study shows that the com plex crystallizes in the m onoclinic space group P 2!/c with a = 896.1(3) pm, b = 2059.9(7) pm , c = 1298.6(6) pm , ß = 91.37(1)° and Z = 4. The nickel is six-coordinate. The distorted octahedral N 4 0 2 arrangement o f donor atom s around the nickel is formed by the tetradentate N 4 m acrocycle TM BC in an unexpected folded form and by a nitrate ion as a bidentate ligand occupying two d e ­ positions. The structure could be refined to the final /?-value of 0.045 only by assuming disorder for the second, noncoordinated nitrate ion.

 Title    Discotic Mesophases of the Hexakis(alkylsulfono)benzene Series: Characterization by Differential Scanning Calorimetry, Optical Microscopy and Nuclear Magnetic Resonance Spectroscopy [1]  
 Abstract    H exakis(alkylsulfono)benzene Series, N M R Spectra M em bers o f the H exakis(alkylsulfono)benzene series 4, containing 7 to 15 carbon atoms per alkyl chain (4 c —k), exhibit one and possibly several liquid crystalline discotic m esophases. The m esophases are uniaxial and m ost probably have a columnar structure. Their anisotropic m agne­ tic susceptibility is negative and in sufficiently strong magnetic fields they align with the director perpendicular to the field direction. Deuterium NM R spectra of C6D 6 dissolved in the m esophases exhibit quadrupolar splittings which are strongly temperature dependent. In analogy with the conventional discotics this suggests the presence o f multiple solvation sites for solute m olecules.

 Title    Elektrochemische Synthesen, XI [1] Katalyse-Anwendung elektrochemischer Systeme: Hydroformylierungsreaktionen Electrochem ical Syntheses, XI [1] Catalysis Application of Electrochemical Systems: Hydroformylation Reactions  
 Abstract    The electrochem ical synthesis of Co2(C O)6(PBu3) 2 and [C o(C O)3(PBu3)2][C o(C O)4] from C o(acac) 2 or cobalt anodes has been investigated. The formation o f the catalytically active species H C o(C O) 4 and H C o(C O)3P Bu3, respectively, by electrochemical reductive carbonylation under conditions suitable for oxo-reactions was ascertained by IR -spectroscopic studies. Further investi­ gations dem onstrate the possibility of sim ultaneous production o f the catalysts and application in hydroform ylation processes with the advantage of reducing the induction period and the amount o f catalyst for equal quantities o f products.
