This research explores the alteration of metal–organic frameworks (MOFs) using a method called postsynthetic metal exchange. We focus on the shift from a Zn-based MOF containing a [Zn4O­(COO)6] secondary building unit (SBU) of octahedral site symmetry (ANT-1­(Zn)) to a Fe-based one with a [Fe3 IIIO­...
