Two examples of heterometallic–organic frameworks (HMOFs) composed of dicarboxyl‐functionalized Fe III ‐salen complexes and d 10 metals (Zn, Cd), [Zn 2 (Fe‐L) 2 (μ 2 ‐O)(H 2 O) 2 ] ⋅ 4 DMF ⋅ 4 H 2 O ( 1 ) and [Cd 2 (Fe‐L) 2 (μ 2 ‐O)(H 2 O) 2 ] ⋅ 2 DMF ⋅ H 2 O ( 2 ) (H 4 L=1,2‐cyclohexanediamino‐ N , N′ ‐bis(3‐methyl‐5‐carboxysalicylidene), have been synthesized and structurally characterized. In 1 and 2 , each square‐pyramidal Fe III atom is embedded in the [N 2 O 2 ] pocket of an L 4− anion, and these units are further bridged by a μ 2 ‐O anion to give an (Fe‐L) 2 (μ 2 ‐O) dimer. The two carboxylate groups of each L 4− anion bridge Zn II or Cd II atoms to afford a 3D porous HMOF. The gas sorption and magnetic properties of 1 and 2 have been studied. Remarkably, 1 and 2 show activity for the photocatalytic degradation of 2‐chlorophenol (2‐CP) under visible‐light irradiation, which, to the best of our knowledge, is the first time that this has been observed for Fe III ‐salen‐based HMOFs.
