 Title    Gläser und Verbindungen im System P4S4-A s 4S4-A s 4Se4-P 4Se4 Glass and Com pounds in the System P4S4-A s 4S4-A s 4Se4-P 4Se4  
 Abstract    Glas forming regions and glass temperatures o f the system P4S4-A s 4S4-A s 4Se4-P 4Se4 have been determined by thermoanalytical and X-ray methods. In the whole system crystalline sam­ ples have been obtained by annealing. From the pure phases A s4S4 and P4Se4 broad regions o f solid solutions extend into the system. In the P4S4 corner the form ation o f A 4B3 (A = P, As; B = S, Se) molecules is observed. As with A 4B3 m olecules, a stepwise substitution o f P by As atoms, and o f S by Se atom s is possible. All molecules o f the series P4_"As"S4 and A s4S4_"Sen (n = 0, 1, 2, 3, 4) were detected by 31P N M R and/or mass spectroscopy.
