    Description / Table of Contents: [Na(12-Crown-4)2]2[Ni(Se4)2] · DMF; Synthesis, Crystal Structure, and Magnetic BehaviourThe title compound has been prepared from NiCl2 and sodium polyselenide in dimethylformamide solution in the presence of 12-crown-4, forming black crystal needles. They were characterized by an X-ray structure determination, by FIR spectroscopy as well as by the magnetic behaviour.[Na(12-crown-4)2]2[Ni(Se4)2] · DMF crystallizes monoclinically in the space group P21, 3650 observed unique reflections, R = 0.046. Lattice dimensions at -80°C: a = 1020.3(2); b = 1889.5(2); c = 1498.7(3) pm; β = 108.29(1)°. The compound has an ionic structure, in which the sodium atoms of the [Na(12-crown-4)2]+ cations are coordinated by the oxygen atoms of the crown ether molecules in an antiprismatic fashion. The nickel atom of the anion [Ni(Se4)2]2- is surrounded by four selenium atoms of the tetraselenide chelates in an almost planar environment. The DMF molecules are inserted in the lattice without a bonding interaction. The magnetic susceptibility observed in the temperature interval 4.2 to 330K can be interpreted by means of a 3E ground term and D2 as local symmetry, which was established by X-ray crystallography.

The presence of N → Zr interaction favours the formation of zirconocene cations. Traces of water cause the formation of the salt-like compound [C5H3N-2,6-(CH2—C5H4)2Zr(Cl)(OH2)]2[ZrCl6] 4 from 2. The new compounds were characterized by 1H n.m.r., and mass spectroscopy. The X-ray crystal structure of 4 shows discrete cations and anions which are connected by H-bridges.
    Notes: Pyridinverbrückte Metallocendichloride des Typs C5H3N-2,6-(CH2—C5H4)2MCl2 (M = Zr (2), Hf (5)) wurden synthetisiert. Aufgrund einer N → Zr-Wechselwirkung wird die Bildung von Zirconocen-Kationen begünstigt. So entsteht bei der Einwirkung von Feuchtigkeit auf 2 die ionisch aufgebaute Verbindung [C5H3N-2,6-(CH2—C5H4)2Zr(Cl)(OH2)]2[ZrCl6] 4. Die Verbindungen wurden 1H-NMR und MS-spektroskopisch charakterisiert. Die Kristallstruktur von 4 läßt eine Verknüpfung der Kationen und Anionen über H-Brückenbindungen erkennen.
