    Description / Table of Contents: Zusammenfassung Die qualitative Auswertung von Daten aus Infrarot- und Elektronenspektroskopie von Nickel(II)-Amin-Komplexen erlaubte die Zuordnung einer oktaedrischen (trans-tetragonalen) Symmetrie mit verschieden abgestuften Kation-Anion-Wechselwirkungen. Substituenten am N-Methyl-Liganden tragen signifikant zur Ligandenkonformation, Komplexsymmetrie und Kation-Anion-Wechselwirkung bei. Aus den elektronenspektroskopischen Daten wurden die ParameterDq,B′,C,C/B′, β35 undZ* für jeden Komplex bestimmt und als Kriterium für eine Reihung der Aminliganden herangezogen.
    Notes: Summary Qualitative infrared and electronic spectroscopic data for a series of nickel(II) amine complexes suggest structures involving octahedral (transtetragonal) symmetry and associated with varying degrees of cation-anion interaction. N-methyl ligand substituents contribute significantly to ligand conformations, complex symmetry, and cation-anion steric interactions. From the electronic data, the parametersDq,B′,C,C/B′, β35, andZ* are determined for each complex and a spectrochemical and nephelauxetic series is proposed for the associated amine ligands.
