[Li(12-Crown-4)]Cl: Crystal Structure and I.R. SpectrumColourless single crystals of [Li(12-crown-4)]Cl were obtained from acetonitrile solutions of LiCl in the presence of 12-crown-4. They were characterized by i. r. spectroscopy as well as by an X-ray structure determination. Space group P4/n, Z = 2, 1 080 observed unique reflections, R = 0.034. Lattice dimensions at -50°C; a = 837.8(5), c = 752.0(2) pm. [Li(12-crown-4)]Cl forms ion pairs with tetragonal symmetry and bond lengths Li—O of 212.8 pm and Li—Cl of 229.0 pm.
Notes:
[Li(12-Krone-4)]Cl wurde aus LiCl-Lösungen in Acetonitril in Gegenwart von 12-Krone-4 in farblosen Einkristallen erhalten, die durch das IR-Spektrum und eine röntgenographische Strukturanalyse charakterisiert werden. Raumgruppe P4/n, Z = 2, 1080 beobachtete unabhängige Reflexe, R = 3,4%. Gitterabmessungen bei -50°C: a = 837,8(5), c = 752,0(2) pm. [Li(12-Krone-4)]Cl bildet Ionenpaare mit tetragonaler Symmetrie und Abständen Li—O von 212,8 pm und Li—Cl von 229,0 pm.
