    Description / Table of Contents: Multiple Center-Bridged Donor-Acceptor complexes of Dimethylmagnesium with F⊖, CI⊖, CN⊖, N3⊖, NCO⊖ und SCN⊖The tetramethylammonium salts [(CH3)4N]⊕X⊖ with X⊖ = F⊖, CN⊖, N3⊖, and NCO⊖ react in ethereal solution with dimethylmagnesium to form the donor-acceptor complexes [(CH3)4N]2{[(CH3)2Mg]2X}2. The vibrational spectra suggest that the complex anions possess the methyl-bridged structures 1 or 4. Equimolar amounts of (CH3)2Mg react with [(CH3)4N]⊕X⊖ (X⊖ = CI⊖, N3⊖, SCN⊖) to yield adducts of composition [CH3)4N]2[(CH3)2MgX]2. The anions appear to have centrosymmetric methyl-bridged structures of the type 5-7.
    Notes: Die Tetramethylammoniumsalze [(CH3)4N]⊕ mit X⊖ = F⊖, CN⊖, N3⊖ und NCO⊖ reagieren mit ätherischen Lösungen von Dimethylmagnesium unter Bildung der Donator-Acceptor-Komplexe [(CH3)4N]2{[(CH3)2Mg]2X}2. In den komplexen Anionen liegen nach den Schwingungsspektren (IR, Raman) Methylbrücken enthaltende Strukturen vom Typ 1 bzw. 4 vor. Durch Anwendung äquimolarer Mengen (CH3)2Mg/[(CH3)4N]⊕X⊖ entstehen mit X⊖ = CI⊖, N3⊖, SCN⊖ Addukte der Zusammensetzung [(CH3)4N]2[(CH3)2MgX]2, deren Anionen methylverbrückte zentrosymmetrische Strukturen vom Typ 5 - 7 aufweisen.

    Description / Table of Contents: Vibrational Spectra of the Cyanodimethylethylmetal Complexes of Magnesium, Aluminium, Gallium, IndiumTetramethylammonium cyanide reacts with an ethereal solution of dimethylmagnesium to form [NMe4]4[Me2MgCN]4, the complex anion of which is isoelectronic with the known tetrameric dimethylaluminium cyanide [Me2AlCN]4. The vibrational spectra are reported together with those of the corresponding gallium and indium compounds.
    Notes: Tetramethylammoniumcyanid reagiert mit in Äther gelöstem Dimethylmagnesium unter Bildung von [Me4N]4[Me2MgCN]4, dessen komplexes Anion mit dem bereits bekannten, ebenfalls tetrameren Dimethylaluminiumcyanid [Me2AlCN]4 isoelektronisch ist. Die Schwingungsspektren werden mitgeteilt und durch die Spektren der homologen Cyanide von Gallium und Indium ergänzt.
