    Description / Table of Contents: Gold Nitrogen Heterocycles. Synthesis, Properties, and Structure of [(CH3)2AuNH2]4 and [(CH3)2AuN(CH3)2]2Dimethyl gold iodide reacts with alkali metal amides to form Au-N heterocycles. KNH2 yields the eight-membered ring [(CH3)2AuNH2]4, whereas with LiN(CH3)2 the four-membered ring [(CH3)2AuN(CH3)2]2 is obtained. The light sensitive, cyclic gold amides are stable against hydrolysis and do not react with Lewis bases. [(CH3)2AuN(CH3)2]2 crystallizes monoclinic in the space group P21/c with Z = 2. The molecules exhibit the symmetry D2h. Symmetrical amido bridges form a planar Au-N heterocyclus with distances Au-N = 214 pm.
    Notes: Dimethylgoldiodid reagiert mit Alkalimetallamiden unter Bildung von Au-N-Heterocyclen. Mit KNH2 entsteht der Achtring [(CH3)2AuNH2]4, während mit LiN(CH3)2 der Vierring [(CH3)2AuN(CH3)2]2 erhalten wird. Die lichtempfindlichen, cyclischen Goldamide sind hydrolysebeständig und reagieren nicht mit Lewisbasen. [(CH3)2AuN(CH3)2]2 kristallisiert monoklin in der Raumgruppe P21/c mit Z = 2. In den Molekülen mit der Symmetrie D2h bilden symmetrische Amidbrücken einen ebenen Au-N-Heterocyclus mit Au-N-Abständen von 214 pm.
