A porous heterotrimetallic organic framework, [BaNa(FeL)₂(渭₂-OH)(H₂O)]路DMF路2H₂O (1) [H₄L = 1,2-cyclohexanediamino-N,N鈥?bis(3-methyl-5-carboxysalicylidene)], has been synthesized and characterized. Each Fe^III ion is embedded in the internal [N₂O₂] pocket of an L^{4鈥?/sup> anion and further bridged by a 渭₂-OH anion to give an (FeL)₂(渭₂-OH) dimer. The external carboxylate groups of L4鈥?/sup> anions coordinate to BaII and NaI atoms to generate a three-dimensional periodic network. The sorption properties and UV鈥搗is spectrum of 1 have been studied. The photodegradation of 2-chlorophenol (2-CP), 3-CP, and 4-CP by 1 at different pH values under visible light has also been systematically investigated.}
