QMOF-1 and QMOF-2: Three-Dimensional Metal–Organic Open Frameworks with a Quartzlike Topology

Man-made minerals: The synthesis of two α- and β-quartz structures with open metal–organic frameworks (QMOF-1 and QMOF-2) is reported. QMOF-1 is assigned to Zn(ISN)2⋅2 H2O (ISN=isonicotinic acid) with the low symmetry of α-quartz, while QMOF-2 to InH(BDC)2 (BDC=terephthalate) with the high symmetry of β-quartz.
