Description / Table of Contents:
Homoleptic Zinc Amides: Transition to Monomeric MoleculesZinc chloride reacts with the lithium salts of the bulky secondary amines HN(i-Bu)2 and HN(t-Bu)2 to form the corresponding homoleptic zinc compounds {Zn[N(i-Bu)2]2}2 (1) and Zn[N(t-Bu)2]2 (2). The NMR spectroscopic and mass spectrometric results as well as the molecular weight determinations and X-ray diffraction data are consistent with a dimeric structure of 1 and a monomeric structure of 2 in the gas phase, in solution and in the solid state.
Notes:
Zinkchlorid reagiert mit den Lithiumsalzen der sterisch anspruchsvollen sekundären Amine HN(i-Bu)2 und HN(t-Bu)2 zu den homoleptischen Zinkamiden {Zn[N(i-Bu)2]2}2 (1) und Zn[N(t-Bu)2]2 (2). Entsprechend der Ergebnisse von NMR-Spektroskopie, Massenspektrometrie, Molmassenbestimmung und Röntgenstrukturanalyse ist 1 dimer, 2 dagegen in der Gasphase, in Lösung und im Festkörper monomer.
