    Description / Table of Contents: On the Knowledge of the New Ionic Ozonides P(CH3)4O3 and As(CH3)4O3P(CH3)4O3 and As(CH3)4O3 were prepared via ion exchange in liquid ammonia and characterized by X-ray-powder, IR, MS and DTA techniques. P(CH3)4O3 and As(CH3)4O3 are isotypic and have a wurtzite-like arrangement of ions with rotationally disordered O3-. (Powder data: P63mc; P(CH3)4O3: a = 687.8(2), c = 964.6(3) pm; As(CH3)4O3: a = 708.6(1), c = 991.0(3) pm). As(CH3)4O3 shows a displacive phase transition at -135°C. The low temperature phase is orthorhombic (a = 715.8(7), b = 1 209(1), c = 943.3(1) pm).
    Notes: P(CH3)4O3 und As(CH3)4O3 wurden mittels Ionenaustausch in fl. NH3 erstmals dargestellt und mit Röntgenpulvermethoden, IR-Spektroskopie, MS und DTA charakterisiert. P(CH3)4O3 und As(CH3)4O3 sind isotyp und bilden eine Ionenpackung im Wurtzit-Typ mit fehlgeordnetem O3-. (Röntgenpulverdaten: P63mc; P(CH3)4O3: a = 687,8(2), c = 964,6(3) pm; As(CH3)4O3: a = 708,6(1), c = 991,0(3) pm). As(CH3)4O3 zeigt bei - 135°C eine displazive Phasenumwandlung. Die Tieftemperaturphase hat orthorhombische Metrik (a = 715,8(7), b = 1 209(1), c = 943,3(1) pm).
