    Description / Table of Contents: Ternary Bromides of Aluminium, Gallium, and Indium of the Formula Type AIMIIIBr4 (AI = Na, Ga, K, In, Rb). An OverviewThe fourteen possible bromides AIMIIIBr4 with AI = Na, Ga, K, In, Rb and MIII = Al, Ga, In are obtained from mixtures of the binary components, ABr and MBr3. Six different structure types are observed: NaGaBr4-, NaAlCl4-, GaCl2-, β-GaBr2-, KAlBr4-, and BaSO4-type. Singlecrystal data are reported for the examples of NaGaBr4, KGaBr4, and InGaBr4. Without exception, slightly distorted tetrahedra [MBr4]- occur. The structural variety must be sought in the adjustment of the coordinational needs of the counter cations A+ (coordination numbers between six and twelve).
    Notes: Die 14 möglichen Bromide AIMIIIBr4 (AI = Na, Ga, K, In, Rb; MIII = Al, Ga, In) erhält man aus Gemengen der binären Komponenten, ABr und MBr3. Es treten sechs unterschiedliche Strukturtypen auf: NaGaBr4-, NaAlCl4-, GaCl2-, β-GaBr2-, KAlBr4- bzw. BaSO4-Typ. Einkristalldaten werden für die Beispiele NaGaBr4, KGaBr4 und InGaBr4 mitgeteilt. Stets liegen (leicht verzerrte) Tetraeder [MBr4]- vor. Die strukturelle Vielfalt ist in der Anpassung an die Koordinationsbedürfnisse der Gegenkationen A+ (Koordinationszahlen zwischen 6 und 12) zu suchen.
