Reversibles Ineinander: Kristalle des Metall-organischen Gerüsts MOF-123 [Zn7O2(NBD)5(DMF)2] haben eine dreidimensionale poröse Struktur, in der DMF-Liganden (rosa im Bild) in kleine Kanäle hineinragen. Entfernt man diese Liganden, so resultiert das doppelt verzahnte Gerüst MOF-246 [Zn7O2(NBD)5], das auf DMF-Zugabe hin wieder in MOF-123 übergeht. NBD=2-Nitrobenzol-1,4-dicarboxylat.
