Two heterotrimetallic organic frameworks [(CH3)2NH2][Cd2Na(Fe-L)2(H2O)6]·4DMF·4H2O (1) and [ZnNa(Fe-L)(H2O)]·2DMF·2H2O (2), have been synthesized via the reaction of a novel tetracarboxyl-functionalized 1,2-ethanediamino-N,N′-bis(3-tertiarybutyl-5-((3,5-carboxybenzyl)oxy)salicylidene) (H6L) Schiff base ligand. In 1 and 2, the internal [N2O2] pockets of L6− anions are embedded by Fe(III) ions, while the external carboxylate groups are ligated by Zn(II)/Cd(II) and Na(I) ions. Both frameworks display fascinating 3D frameworks. The photodegradation properties of 1 and 2 towards 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) under visible light have been systematically investigated. Their magnetic behaviors have also been studied.
