    Description / Table of Contents: Pseudochalkogeno Compounds. XXIII. On the Dicyanomethanide-Ion, [C(CN)2]2--Synthesis and ReactivityThe preparation of metal dicyanomethanides, M2[C(CN)2] is reported. Infrared spectra of the compounds as well as the reactivity of Li2[C(CN)2] - phosphorylation and organometalation reactions have been investigated - are indicating an non-linear structure of the anion. For organophosphoryl-dicyanomethanides, {(RO)2P(O)}2C(CN)2 a further synthetic route is described which supports this structure proposal for the pseudochalconide anion [C(CN)2]2-.
    Notes: Es wird über die Darstellung von Metalldicyanmethaniden M2[C(CN)2](M: Li, Na, Ag) berichtet. Die IR-Spektren der Verbindungen weisen ebenso wie die Reaktivität von Li2[C(CN)2] - untersucht wurden Phosphorylierungs- und Organometallierungsreaktionen - eine winklige Struktur des Dicyanmethanid-Ions [C(CN)2]2- aus. Für Bis-(Organophosphoryl)-dicyanmethanide {(RO)2P(O)}2C(CN)2 wird ein weiterer Syntheseweg angegeben, der die Strukturvorstellungen für das Pseudochalkogenid-Ion [C(CN)2]2- unterstützt.

    Description / Table of Contents: Pseudoelement Compounds. I. Coordination Behaviour of Diphenyl-cyanamido-thiophosphinateThe synthesis of the cyanamido-thiophosphinate-nickel(II) complexes NipynX2 (X = Ph2P(S)NCN, n = 0, 2, 4) is reported and the i.r. and u.v. spectra of these compounds are discussed. The single crystal X-ray analysis of the tetrapyridine complex shows that the anionic ligand is coordinated via the cyano-nitrogen atom. With a bond angle N(1)—C(1)—N(2) of 175.4(3)° the NCN group is nearly linear. The bond distances N(1)—C(1) and C(1)—N(2) are asymmetric and typical of NC double and triple bonds.
    Notes: Die Synthese von Cyanamido-thiophosphinat-nickel(II)-Komplexen NipynX2 (X = Ph2P(S)NCN, n = 0, 2, 4) wird beschrieben und die IR- und UV-Spektren dieser Verbindungen werden diskutiert. Die Einkristall-Röntgenstrukturanalyse des Tetrapyridin-Komplexes zeigt, daß der anionische Ligand über das Cyano-Stickstoff-Atom koordiniert ist. Die NCN-Gruppe ist mit einem Winkel N(1)—C(1)—N(2) von 175,4(3)° nahezu linear. Die Bindungsabstände N(1)—C(1) und C(1)—N(2) sind asymmetrisch und typisch für NC-Doppel-bzw. Dreifachbindungen.
