    Description / Table of Contents: Elektrochemische Synthese von Nickel(II)-Komplexen mit Schiffschen Basen: Kristallstruktur von 2,2′-Bipyridin-bis{2-[(phenyl)iminomethyl]pyrrolato}nickel(II)Die elektrochemische Oxidation von anodischem Nickel in einer Acetonitril-Lösung mit einer aus H-pyrrole-2-carbaldehyd abgeleiteten Schiffschen Base, einem substituierten Anilin und einem Stickstoff-Liganden (1,10-Phenanthroline (phen), 2,2′-Bipyridin (bipy) oder Pyridin (py)) liefert die gemischten Komplexe NiL2 · phen, NiL2 · bipy bzw. NiL2 · (py)2. Die Kristallstruktur von 2,2′-Bipyridin bis{2-[(phenyl)iminomethyl]-pyrrolato}nickel(II) wurde röntgenographisch bestimmt. Der. Komplex kristallisiert triklin in der Raumgruppe P1, mit den Gitterkonstanten a = 12,316(1), b = 13,169(4), c = 17,251(3) Å, α = 82,67(3)°, β = 83,66(1)°, γ = 87,34(2)°, Z = 4; besteht aus monomeren Molekülen mit der zentralen NiN6-Einheit mit verzerrt oktaedrischer Geometrie.
    Notes: The electrochemical oxidation of anodic nickel in acetonitrile solution containing both (a) a Schiff base HL derived from H-pyrrole-2-carbaldehyde and a substituted aniline, and (b) a nitrogen ligand (1, 10-phenanthroline (phen), 2,2′-bipyridine (bipy) or pyridine (py)) yielded the mixed complexes NiL2 · phen, NiL2 · bipy and NiL2 · (py)2. The crystal structure of 2,2′-bipyridine bis{2-[(phenyl)iminomethyl]pyrrolato}nickel(II) was determined by X ray diffraction. Crystals are triclinic space group P1, with four molecules in the unit cell of dimensions a = 12.316(1), b = 13.169(4), c = 17.251(3) Å, α = 82.67(3)°, β = 83.66(1)° and γ = 87.34(2)°, and consist of monomeric molecules in which the central NiN6 unit has a distorted octahedral geometry.
