    Description / Table of Contents: New Complex Metal FulminatesThe preparation and infrared spectra of non explosive, thermally stable tetraphenyiarsonium or tetraalkylammonium salts of the fulminate complexes [Ru(CNO)6]4-, [OsO2(CNO)4]2-, [Rh(CNO)6]3-, [Ir(CNO)6]3-, [Zn(CNO)4]2-, [Cd(CNO)4]2- are described. Other anions, e. g. [M(CNO)4]2 (M = NiII, PdII, PtII). [(M(CNO)2]- (M = AgI, AuI) are also stabilisized by large cations. (R3P)2\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm M}\limits^{{\rm + 2}} $\end{document}(CNO)2 (M = Pd, Pt) and [AsPh4][A\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm u}\limits^{{\rm + 1}} $\end{document}(CNO)2] react with bromine or iodine to give the „mixed“ complexes (R3P)2\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm M}\limits^{{\rm + 4}} $\end{document}(CNO)2X2 and [AsPh4]-[A\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm u}\limits^{{\rm + 3}} $\end{document}(CNO)2X2], respectively (X = Br, J). Irradiation of the hexacarbonyls M(CO)6 (M = Cr, Mo, W) in the presence of fulminate ion in THF yields difulminatotetracarbonylmetallates(O), cis-[M(CO)4(CNO)2]2-, which are the first examples of fulminato complexes containing the metal in a low oxidation state.
    Notes: Die Darstellung und IR-Spektren von nicht explosiven, thermisch recht stabilen Tetraphenyl-arsonium- oder Tetraalkylammonium-Salzen der Fulminato-Komplexe [Ru(CNO)6]4-, [OsO2(CNO)4]2-, [Rh(CNO)6]3--, [Ir(CNO)6]3-,- [Zn(CNO)4]2-, [Cd(CNO)4]2- werden be-schrieben. Auch andere Fulminatometallat-Anionen wie [M(CNO)4]2- (M = NiII, PdII, PtII), [M(CNO)2]- (M = AgI, AuI) lassen sich durch großvolumige Kationen stabilisieren. Die Verbindungen (R3P)2\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm M}\limits^{{\rm + 3}} $\end{document}(CNO)2 (M = Pd, Pt) sowie [AsPh4][A\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm u}\limits^{{\rm + 1}} $\end{document}(CNO)2] reagieren mit Brom oder Jod unter oxydativer Addition des Halogens zu den „gemischten“ Komplexen (R3P)2\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm M}\limits^{{\rm + 4}} $\end{document}(CNO)2X2 bzw. [AsPh4][A\documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm u}\limits^{{\rm + 3}} $\end{document}(CNO)2X2] (X = Br, J). Bei der photochemischen Umsetzung der Hexacarbonyle von Chrom, Molybdän und Wolfram mit dem Fulminat-Ion in THF entstehen die Difulminatotetracarbonylmetallate(0), cis-[M(CO)4(CNO)2]2-, als erste Vertreter von Fulminato-Komplexen mit niedriger Oxydationszahl des Metalls.
