| Abstract: | Two examples of heterometallic–organic frameworks (HMOFs) composed of dicarboxyl‐functionalized FeIII‐salen complexes and d10 metals (Zn, Cd), [Zn2(Fe‐L)2(μ2‐O)(H2O)2] ? 4 DMF ? 4 H2O ( 1 ) and [Cd2(Fe‐L)2(μ2‐O)(H2O)2] ? 2 DMF ? H2O ( 2 ) (H4L=1,2‐cyclohexanediamino‐N,N′‐bis(3‐methyl‐5‐carboxysalicylidene), have been synthesized and structurally characterized. In 1 and 2 , each square‐pyramidal FeIII atom is embedded in the [N2O2] pocket of an L4? anion, and these units are further bridged by a μ2‐O anion to give an (Fe‐L)2(μ2‐O) dimer. The two carboxylate groups of each L4? anion bridge ZnII or CdII 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 FeIII‐salen‐based HMOFs. |
