    Description / Table of Contents: Preparation, Vibrational Spectrum, and Crystal Structure of Dimeric (Isopropylideneamino) dimethylindiumThe title compound [Me2C=N—InMe2]2 was prepared from N-chloro-2-propanimine and trimethylindium. Its IR and Raman spectra were assigned; together with the 1H-NMR spectrum and the mass spectrum a centrosymmetric molecular structure with a four-membered (InN)2 ring was deduced. This was confirmed by an X-ray structure determination, according to which there exist two dimeric molecules per unit cell in the space group P21/c. The structure was refined with 958 reflexions up to a residual index of R = 0.024.
    Notes: Die Titelverbindung [Me2C=N-InMe2]2 wurde aus N-Chlor-2-propanimin und Trimethylindium synthetisiert. Das IR-und Raman-Spektrum wurde zugeordnet; zusammen mit dem 1H-NMR- und dem Massenspektrum ergibt sich eine zentrosymmetrische Molekülstruktur mit einem (InN)2-Vierring. Dies wird durch die Röntgenstrukturbestimmung bestätigt, nach der eine Struktur mit zwei dimeren Molekülen pro Elementarzelle in der Raumgruppe P21/c vorliegt. Die Struktur wurde bis zu einem Übereinstimmungsindex von R = 0.024 für 958 Reflexe verfeinert.

    Description / Table of Contents: Preparation and Vibrational Spectra of Dimeric (Isopropylidenamino)dimethylborane, -alane, and -gallaneN-Chloro-2-propanimine (1) reacts with trimethylboron, -aluminium, and -gallium to form the dimeric imino compounds [Me2C=N—MMe2]2 (M=B, Al, Ga) (2-4), which, according to the vibrational spectra, occur as M2N2 four-rings of the point group D2h. Also, the vibrational spectrum of 1 is reported.
    Notes: N-Chlor-2-propanimin (1) reagiert mit den Trimethylverbindungen von Bor, Aluminium und Gallium unter Bildung der dimeren (Isopropylidenamino)dimethyl-Derivate [Me2C=N—MMe2]2 (M=B, Al, Ga) (2-4), die nach den Schwingungsspektren zentrosymmetrische M2N2- Vierringe (Symmetrie D2h) bilden. Das Schwingungsspektrum von 1 wird ebenfalls mitgeteilt.
