Abstract

Gasteinschluss und Spin: Das mikroporöse Koordinationspolymer {Fe(pz)[Pt(CN)4]} (1, pz=Pyrazin) enthält Spin-Crossover-Untereinheiten und kann als chemischer Schalter verwendet werden, der bei Raumtemperatur zwischen zwei magnetischen Zuständen wechselt. Magnetische Messungen unter Bedampfung belegen, dass die Einlagerung der meisten Gastspezies 1 aus dem Low-Spin(LS)-Zustand in den High-Spin(HS)-Zustand überführt; allein CS2 bewirkt den umgekehrten Übergang von HS nach LS.
