Abstract: | ![]() On the Knowledge of the New Ionic Ozonides P(CH3)4O3 and As(CH3)4O3 P(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). |
