    Description / Table of Contents: [(S)-tert-Butylmethylphenylphosphine][(+)-(1R,5R-3-2-10-η-pinenyl]nickel Bromide, C10H14NiBrP(CH3)3(C6H5) Molecular Structure and Absolute ConfigurationThe X-Ray structural analysis of the compound 2 show a square planar arrangement of the ligands around the nickel atom. The pinene part of the molecule is linked to the metal in exoposition via a non-symmetric π-allyl-group. The more positions at the nickel atom are occupied by bromine and phosphorus. The arrangement of the substituents at the phosphorus atom is essentially tetrahedral with identical C-P-C angles (104.6°), but different C-P-Ni angles (106-122°). The absolute configuration has been determined with more than 99.9% probability.
    Notes: Die Röntgenstrukturanalyse der Titelverbindung 2 ergab eine quadratisch planare Anordnung der Liganden am Nickel-Zentralatom, wobei der Pinen-Rest über eine unsymmetrische π-Allyl-Gruppierung in exo-Stellung am Nickel fixiert ist. Zwei weitere Koordinationsstellen des Nickels werden durch Brom und Phosphor besetzt. Die Anordnung der Substituenten am Phosphor ist verzerrt tetraedrisch mit nahezu identischen C-P-C-winkeln (104.6°), jedoch stark unterschiedlichen C-P-Ni-Winkeln (106-122°). Die absolute Konfiguration der Verbindung wurde mit über 99.9 proz. Wahrscheinlichkeit aus den Beugungsdaten abgeleitet.
