    Description / Table of Contents: Crystal and Molecular Structures of (Me2SiNCN)4 (1) and Me3SiNCNSiMe3 (2)Synthesis, spectroscopic characterization (NMR, IR, Raman and MS) and crystal structure of the novel compound 1 are described. The molecules form almost planar 16 membered rings with four SiMe2-groups connected to four NCN groups. The corresponding compound 2 exhibits a phase transition from the HT phase 2a to the LT phase 2b at 131 K. Consecutive X-ray structure determinations of the molecular structures of both modifications were performed on a crystal, grown in situ on the diffractometer at 231 K.
    Notes: Für die neuartige Verbindung 1 werden Synthese, spektroskopische Charakterisierung (NMR, IR, Raman und MS) und die Kristallstruktur beschrieben. Das Molekül besteht aus einem nahezu planaren 16gliedrigen Ring, in dem vier SiMe2-Gruppen mit vier NCN-Gruppen verknüpft sind. Die Vergleichsverbindung 2 zeigt eine Phasenumwandlung von der HT-Phase 2a in die TT-Phase 2b bei 131 K. Die Molekülstrukturen beider Modifikationen wurden nacheinander durch Röntgenstrukturanalyse an einem in situ bei 231 K auf dem Diffraktometer gezüchteten Kristall bestimmt.
