    Notes: Syntheses, Properties, and Crystal Structures of the Titanium(III) Amido Complexes Ti[N(SiMe3)2]3, [TiCl2{N(SiMe3)2}(THF)2], and [Na(12-Crown-4)2][TiCl2{N(SiMe3)2}2]TiCl3(THF)3 reacts with NaN(SiMe3)2 to furnish [TiCl2{N(SiMe3)2}(THF)2] (1), whereas in the presence of 12-crown-4 the ionic amido complex [Na(12-crown-4)2][TiCl2{N(SiMe3)2}2] (5) is obtained besides [Na(12-crown-4)2][TiCl4(THF)] (4). On the other hand, the titanium(III) amido complex Ti[N(SiMe3)2]3 (2), the crystal structure of which was solved, reacts with NaN(SiMe3)2 in the presence of 12-crown-4 with deprotonation of one of the methyl groups to give the carbometalated complex [Na(12-crown-4)2][Ti{N(SiMe3)2}2{N(SiMe 3CH2)}] (3).

    Description / Table of Contents: [Li7(CHPMe2NSiMe3)3(OSiMe2nBu)]2, a Mixed-Ligand-Li14 Cluster with the Carbdianion (CHPMe2NSiMe3)2-The title compound is formed as colourless moisture and oxygen sensitive crystals by the reaction of [LiCH2PMe2NSiMe3]4 with zinc or cobalt chloride in a toluene suspension in the presence of silicongrease (-OSiMe2-)n and n-butyllithium. It is characterized by multinucleus NMR spectroscopy and by crystal structure determinations of two different crystal individuals.1. Space group P1, Z = 1, lattice dimensions at -70 °C: a = 1272.0, b = 1392.6, c = 1417.6 pm, α = 115.33°, β = 96.75°, σ = 106.81°; R = 0.042.2. Space group P21/n, Z = 2, lattice dimensions at -50 °C: a = 1424.8, b = 1457.1, c = 1997.0 pm, β = 90.32, R = 0.069.
    Notes: Die Titelverbindung (farblose, feuchtigkeits- und sauerstoffempfindliche Kristalle) entsteht bei der Reaktion von [LiCH2PMe2NSiMe3]4 mit wasserfreiem Zink- oder Cobaltchlorid in einer Toluolsuspension in Gegenwart von Siliconfett (-OSiMe2-)n und n-Butyllithium. Sie wird durch Multikern-NMR-Spektroskopie und durch Kristallstrukturanalysen zweier kristallchemisch verschiedener Individuen charakterisiert.1. Raumgruppe P1, Z = 1, Gitterkonstanten bei -70 °C: a = 1272,0; b = 1392,6; c = 1417,6 pm; α = 115,33°; β = 96,75°; σ = 106,81°; R = 0,042.2. Raumgruppe P21/n, Z = 2, Gitterkonstanten bei -50 °C: a = 1424,8; b = 1457,1; c = 1997,0 pm; β = 90,32°; R = 0,069.
