Abstract (English)

The host/guest clathrate systems - [(ZnI2)6(ZnQ)]/[Pn4Qx] (Pn = P, As ; Q = S, Se) are obtained by one-step or two-step reaction of stoichiometric amounts of ZnI2, Pn, and Q or varying Q, I amounts in evacuated silica ampoules. The compounds consist of monomeric alpha-Pn4Q3 and alpha-Pn4Q4 cage molecules which are separated by a cubic host lattice of [(ZnI2)6(ZnQ)]. This contains almost spherical ...

Die host/guest-Clathratsysteme [(ZnI2)6(ZnQ)]/[Pn4Qx] (Pn=P, As; Q=S, Se) werden erhalten aus ein- oder zweistufigen Reaktionen der stöchiometrischen Mengen von ZnI2, Pn und Q oder variablen Mengen an Q, I in evakuierten Quarzglasampullen. Die Verbindungen bestehen aus monomeren alpha-Pn4Q3 und alpha-Pn4Q4 Käfigmolekülen, die durch ein kubisches Gast-Gitter aus [(ZnI2)6(ZnQ)] voneinander ...
