 Title    ( rf-C5Me5)T a F4 * H N = P Ph3 Preparation and Structure of the Adduct (7 5-C5M e5)TaF4 * HN = PPh3  
 Abstract    C p*TaF4 (1) (Cp* = ^5-C5M e5) forms a Lewis acid Lewis base adduct with the im inophos­ phorane H N = PPh3 (2). The adduct C p*TaF4-N H = PPh3 (3) is remarkably stable to thermal decom position. The X-ray crystal struc­ ture o f 3 was investigated.

 Title    Neue Cyclophosphazene mit Metallen der III. Hauptgruppe als Ringbausteine  
 Abstract    Acylic silylated phosphazenes of the type HN(PR2NSiMe3)2 (1) react quantitatively with molecules MMe3 (M = Al, Ga, In) under ring formation and CH4 evolution. The ring com­ pounds N(PPh2NSiMe3)2AlMe2 (2 a) and N(PPh2NSiMe3)2InMe2 (4 a) have been investiga­ ted by X-ray structure determination. 2a and 4a crystallize in the space groups P 1 and P 3 15 respectively; they show different conformations regarding the cyclohexane framework. NMR spectroscopy of the nuclei in the chelating phosphazene ligand indicates decreasing Lewis acidity of the metal containing fragments in the series AlMe2 > GaMe2 > InMe2.
